Doing 5 nights at Disney and scheduled to move to HRH for last day and stay one night. After reading about IOA I figured it was best bet for for us and DS(4yo). Recently I was reading the boards about the different characters that are around and heard that Rugrats, Rocket Power gang, and Shrek are around too. My question to the experts: Should I stay 2 days and do both US/IOA? Is there enough to do at US for 4yo? Do the characters go to both parks? If anybody saw rugrats or rocket power, where? We will be arriving disney 11/06/02 stayin at the GF and were planin to go to HRH on Monday mornin. Now we are go with the flow type people and enjoy spending time at the Pool and seeing the sights. Thanks for any help!
