Everyone has different opinions on what will make a great trip.
We love WDW and love the cruise, but I'd never do both in a week. Too little time with either, too much packing. Of course, other people love the land/sea. (BTW, its late to book May already for the cruise - be prepared for second seating for dinner and a fairly expensive trip - check out the cruise boards. We are already booked for October 2006).
Generally, people do better finacially booking each part seperately. However, some people like having a
travel agent buy them a package - sometimes even including meals. Even if its more expensive, the lack of thinking is good.
I'd start with research. Personally, I like the Passporter as the best book and dislike the Unofficial Guide. Neither has a lot of information on the cruise, although the Passporter people also publish a cruise book. You can also find a lot of information here, at the parent site here (
www.wdwinfo.com), at
www.allearsnet.com and on the Disney web site (
www.disney.com). I'd spend an hour at the bookstore browsing (or go to the library) to find the best one for you, so you don't spend $20 on a guidebook you dislike.
I'd then do a budget. That might determine a lot of what you choose to do. If you haven't started, you may be shocked to discover how much tickets will run you, for instance, and that may determine if you stay in a Value resort on site, a condo off site, or a deluxe on site.
Then I'd make a list of the things that are important to everyone. If everyone wants a relaxing vacation, a cruise may be the way to go. If they want lots of exciting thrill rides - go to Six Flags, that isn't Disney. For most people WDW will be long days, lots of walking, lots of entertainment, and lots of fun and magic. However, Disney is a resort as much as as several theme parks, so its possible to have a relaxing vacation at Disney - its even possible to do quite a few thrill rides.
Once you get those things down, come back (come here while you get those things down) and the lovely DISers will be able to give you great advice. When you can narrow things down to "we've decided to stay at a Moderate - which has the best pool" or "should we get connecting rooms on the ship, or is a category 4 the way to go" or "we think we'd like an offsite condo, any recommendations" it will be easier to give specific advice.
Conventional Wisdom is the best pool on property is Stormalong Bay at the Yacht and Beach Club. Its huge - makes my hair turn grey thinking about trying to watch my kids there. But it has a great slide (all Moderate and Deluxe resorts have pool slides, values do not), a lazy river, a sand bottom. I've been to that pool, the pool at BW, the pool at CBR and the pool at WL. My favorite is the BW pool, which has a great slide and is easier to watch kids at. The pool at WL is beautiful, but the slide is tame. POFQ is supposed to have a the best pool of the moderates - I haven't been - and has rooms that will sleep five - although it will be tight and you'll have one bathroom. The pools on the ship are small and shouldn't be a central point in anyone's vacation plans. Your kids will be too old for the Mickey slide on the ship and the Goofy pool is small and crowded.
