We have 3 kids and have stayed at every level from value to deluxe and are now
DVC. We usually travel in August as well. I would go with the value rooms for the following reasons:
- The skyliner will be down frequently in August which negates any benefit (and also the extra cost) of staying at POP. We won't use our DVC points for anything longer than a night or 2 at RIV because of the skyliner weather issues, it takes awhile to get the busses started on those routes when they make the decision to shut down the skyliner
- Slide or no slide, young kids will still have fun in a value resort pool. Your kids are young enough where they don't know what they are missing regarding pools at other resorts, so a value pool is fine.
- AS movies has such good theming for the price, other than AoA it is the most in your face Disney themed resort. When we had 3 kids ages 6 and under, that resort was our favorite
Since you were in the ICP, you know what August weather is like. Make sure you have a rain cover for the stroller, stroller fan, etc. We went yearly in August with 3 young kids- we took precautions, survived and even had fun. Plan for lots of breaks, stay hydrated and enjoy those air conditioned attractions as much as possible.
You can spend time at other resorts but not at their pools. Take a look at the monthly resort activity guides. AKL has free animal and cultural activities for kids to enjoy (you don't have to stay at AKL or any of the resorts to participate in the activities they offer). Fort Wilderness also has great kid friendly activities for a fee like gem mining and pony rides. Check out DVC community halls for crafts, games and other activities (the ones at AKL, SSR and BLT are our favorites but they are all a lot of fun- you do not have to be a DVC member to enjoy the activities there).
