I'm getting really excited but nervous now. We fly 11 weeks today from Manchester on the Thomson Dreamliner. It will be our first trip to Orlando (infact to the states). Travelling with my hubby and 8 year old Autistic son, staying at the Doubletree Seaworld. I'm really nervous about the flight, hate flying I do it every year but usually just short 2/3 hour flights. Anyway just wondering if anyone had any tips for us first timers ? We are planning on visiting Universal (both parks), Disney (Magic Kingdom, Hollywood Studios and Animal Kingdom) also Seaworld.
