We have been to the 4 Disney parks and are thinking of US/IOA this summer. We were at US about 7 years ago and didn't cover it in 1 day. Which WDW park would you say is closest in size to IOA? I know crowds are a factor etc., but we will have FOTL acces(if RPR opens on time) and are planning on purchasing the 5 day bonus pass. We want to have down time to enjoy the resort ..our kids are 7 & 11. Will we run out of things to do? This is a last minute type trip and we can't afford to add any other parks or major attractions...so we plan to fill in time at the pool(s). Thanks for any opinions...Anyone else brave enough to be at RPR on the 18 of June?
