The Universal Island's of Adventure Theme park has 5 "Islands" and WWoHP is one of those Islands. The previous post stated about half a day to really take your time in that area of Islands of Adventure, which should be plenty. The wait times for the rides can get a bit lengthy ( we waited 25 minutes for the Forbidden Journey, 20 minutes for the Hippogriff, and 60 minutes for Olivander's Wand shop showing - which was worth it since my son was chosen to receive the wand during the show!). Other Islands of Adventure favorites are the water rides on a hot day - You will get soaked on RipSaw! The 8th Voyage of Sindbad show was also very good. Jurassic Park water ride was great too. The park has much to do for the day to make the $85 fee worth it, in my opinion. We visited on a Friday in June as spent the entire day. Going back into WW0HP in the evening was cool - much different than in bright daylight. Have fun!
