Please help. We already have room reservations for our vacation 8/19-8/23. We are planning on going to US/IOA from the 20th-23rd(only until about 3 the last day, since our flight leaves at 6). We may go for a couple of hours on the 19th as well, depending on how tired we are. I was looking into buying Express Passes for Sat and Sun, thinking those two days would be quite busy, but can't fathom paying an extra $40/pp(there are 5 of us) for one days use. I can get a room for $234 at RPR even though we don't need it and that would give us two days of unlimited express passes for the weekend, still alot of money. Wondering if we take it easy, and just get free express passes in the morning for busiest attractions, will four days be enough time to enjoy the parks. My children are smaller, so we will not be able to do hulk, dueling dragons or Fearfall regardless. All thoughts are appreciated. P.
