some answers to the great questions. Sorry I should have been more detailed.
Daughter is 10 and son is 7 . Most of my life savings is going to a Disney Cruise that we're taking after the 3 night stay in DisneyWorld
I want someplace with a great pool for the kids because I'm guessing after 3 days park hopping in July we're gonna need it lol
Now knowing your kids ages, if you guys haven't been to Disney yet, I still recommend the Contemporary or Bay Lake Towers (at the contemp), theme park view. There's nothing like looking over Magic Kingdom at nighttime from your room. It's as *disney* as you can get! The Contemporary also has a great splash area for kids (not just toddlers). Last time we were there 2 years ago, dd was 10 and ds was 8, and they LOVED it. The pool is also great with fountains in it, and a good slide. I haven't been to BLT yet, so I can't specifically comment on the pool.
While Beach Club has the largest pool complex on property, much of it is for older kids, or you being "right" with your kids. The lazy river section is 8' deep (someone correct me if I'm wrong). The entrance to the awesome slide is literally outside of the pool complex, on the boardwalk. You couldn't sit and relax and watch your kids in the pool while they go on the slide. The shallow part of the pool is really great, with a sandy bottom, but it's very, very shallow, so really for smaller kids. I loved Storm-along-bay (the Beach Club pool complex) when mine were little enough to only stay in the shallow sandy bottom section of the pool (when they were 5-ish). We then avoided that complex for a few years and enjoyed other resorts. We'll go back soon, now that the kids are older and can go together out of the complex to the entrance for the pool slide (out of my sight). I may be neurotic... I'm sure some people would let their kids go younger than I let mine... so you may be fine with it. It is really a beautiful pool complex, but very large and deep in areas.
I think your kids will love that Chef Mickeys is in the Contemporary lobby, and that the monorail goes right through the building. It's just a fun, lively building.
Good luck deciding!





Otherwise I would totally agree that a few more days would be wonderful!

Love your opening post .... I always say, a trip to Disney seems so simple UNTIL you find this place!
