I booked an exec suite for me and kids for August through the 4th night free promo. It looked perfect for the 3 of us - DS could have the sofa sleeper. Now DH is coming for half the time, so we tentatively booked SSR for the day following our first (okay, complicated, but the first night is paid for with a nonrefundable deposit). But I don't think we NEED SSR (1 br villa) although it's nice to have the kitchen and washer/dryer. That all being said, the website says the exec suite is 714 square feet - that is quite large. About the same size as the Saratoga Springs villa actually, for less than half the price.
For 4 adults, unless a couple are small or very cuddly, they may not like sharing the sofa sleeper. I asked, and they don't have rollaways, so I'm bringing a twin aerobed for DD, while DH is there. My kids don't do well sharing a bed. I think they have bigger suites, but they told me the price was a lot more (I'm only paying $105/night plus we get free breakfast). The other suites were about triple that price.
My concern is the pool - does it get crowded? Are there lifeguards? I am concerned with the safety. But with the money we're saving, we may actually do a water park (never did one before with the kids, as the resort pools are always enough). I'd love to hear feedback on the pools.
