im going to islands of adventure for 1 day with my kids, and i have a back injury. I understand I cant ride much, no roller coasters or anything thats going to hurt me in any way, but is there anything small or gentle at universal that I would be able to ride? Ive never been there before, have no idea what to expect or what the rides are like. Ill also be at disney but im familiar with those rides and know which ones Id be able to tolerate and which ones wouldn't be appropriate. Thanks
