Hello, I am a frequent poster to the Disney side of the boards but am new to the Universal Portion. I am planning our June vacation with plans to visit Disney for 5 days. Our son is getting to the age 5 ( 6 in August) where he has interest in the Superheros, Scooby and the like so I was thinking of maybe a 1 day/2 park pass for Universal for Sunday of our trip. I have a few questions: 1) How busy are Sunday's in the parks (this will be May 31st)? 2) What rides have baby swap? 3) Do any of the coasters have seats that are accessible for guest of bigger than average size (pooh-sized)? We went to US and IOA several years ago and I had a horribly embarrasing experience on DD and ROTM, I was able to ride but not w/o humiliation. Most likely we won't do many coasters as we will focus on rides we can do as a family but I would love to ride ROTM. TIA!!
