In a previous post, I covered ways you can save money when booking your Disney cruise. Here are a few more ideas for saving money while aboard.

Keep it simple. A friend who took the western Caribbean cruise booked an excursion at every port—and regretted it. Excursion costs tend to be high, particularly if you book with the cruise line, and they often aren’t necessary to have a great time. We booked just one real excursion, a day-long snorkel trip, that we found using TripAdvisor. We also bought the “extreme getaway” package for Castaway Cay (a “stingray adventure” and rental of snorkel equipment, bikes and floats) which turned out to be extreme overkill. I was the only one to ride a bike, and nobody took advantage of the floats. The stingray encounter was cool, though, and Disney’s snorkel garden is not to be missed.

Another option at most ports is to simply wander off the boat and try to arrange an excursion, but our experience is that the best providers are often booked up by the time the ship arrives.

Don’t save at another’s expense. Disney adds $12 per person per day to cover tips for the people who clean your stateroom, serve your meals and keep the ship looking tidy. That added up to $336 for our party of four. You can add to this tip amount—we did—plus you’ll also need tip money for:

• porters who help you with your bags at the port,
• your guides on excursions and
• the waiters who bring room service and who serve you at the adult-only restaurants.

Don’t like to tip? There’s a simple solution: don’t cruise. There are plenty of do-it-yourself vacations where you can reduce or eliminate tipping. When you cruise, though, tips are part of the package and an essential supplement to the low wages most cruise workers earn.

Beware the budget busters. Unlike most other cruise lines, Disney doesn’t charge extra for sodas at meals—but it does charge for alcohol, and that can add up fast. Visits to the spa can add several hundreds of dollars to your bill, as can professional photography and Disney souvenirs.

You can choose to eschew these extras or budget for them in advance. For example, we set a $15-per-day limit for spending for our tween daughter and her friend that they used for popcorn (movie snacks are extra), stuffed animals and pins (trading Disney pins on board with cruise employees and other guests was a favorite activity). My husband and I also bought week-long passes to the spa, which was well worth the charge of about $100 per person. We ate at the adults-only restaurants Palo ($35 per person supplement) and Remy ($85 per person) and enjoyed them immensely.

You can use your stateroom key to charge just about anything you want to buy to your room, which is convenient and dangerous at the same time. The guest services desk will give you printouts of your bill any time you ask so that you won’t be surprised by how very much these add-ons add up by the end of your trip.

If your kids aren’t bugging you about taking a Disney cruise, then either you don’t have kids or they can’t talk yet. The idea that any child would be immune from Disney’s marketing might is hard to fathom.

Disney cruises are pricier than most others for good reason, as I explained this week in my Reuters column “How to get a Disney cruise for less.” Disney markets to families but aims for a luxury experience several cuts above the bargain brands. The company also uses demand pricing, so fares tend to go up over time, not down.

We took our first Disney cruise last month after (of course) extensive research and reading just about every “tips and tricks” article I could find. We scored a decent deal on our fare, but we also made a mistake or two—so I hope you can learn from those as well.

Here’s what we learned:

Go when others can’t. Most families have to book during school breaks. If you can go later or earlier, you can get lower fares. Our fare for two adults and two tweens in a stateroom with a balcony was about $6,000 for a 7-night eastern Caribbean route at the end of August, when many kids are already back at school. The Dec. 19 sailing for the same cruise costs twice that. (Actually, fares currently range from about $9,700 for an inside stateroom to about $31,000 for a one-bedroom concierge suite).

Inside is okay. While the veranda was nice, Disney’s inside cabins may be a better deal since you’ll spend far more time outside of your stateroom than in it. Inside cabins are usually the first to sell out, though, so you’ll need to plan in advance.

Check for deals. Mousesavers, an excellent tip site for all things Disney, keeps a running list of “Great Dates” that offer especially good fares.

Consider shorter cruises. The per-night cost tends to shrink when you take longer cruises. But the 3- and 4-night itineraries can give you a taste of Disney cruising for less overall. The Caribbean and Bahamas routes include a stop at Castaway Cay, Disney’s private island in the Bahamas that’s a real highlight.

Take the bus (or a limo). Disney figured out that one of the biggest downers of cruising (and traveling in general) is dealing with the luggage. So if you book their transfer service, they’ll whisk your bags from the airport baggage claim to your stateroom while your family rides to the port on a luxury bus. The cost is $70 per person, though, so I tried to save a few bucks by renting a car. The one-way rental cost was less than $75, but picking up and dropping off the vehicle would have been a major hassle even if I hadn’t run into a massive traffic jam caused by a brawl at another rental car company. If bus travel isn’t your thing, another option to consider is a private sedan or limo. (Again, Mousesavers has recommendations.)

I have a few more tips for saving money once you’re on the ship that I’ll post later this week.
