I am coming to Orlando alone to visit USF/IOA for the first time and also Sea World Orlando. I will be there from 2-6 through 2-9 and am trying to decide between a 2 day Universal Pass or 3 Day Pass and debating whether or not to do Discovery Cove (will I have fun alone?) and Sea World. Does anyone know what the "line waiting time" is right now at IOA and USF? Should I plan 2 or 3 days to enjoy some attractions twice? Is Discovery Cove really oriented toward families and/or couples or would I enjoy being there alone? I don't want to spend the money unwisely at Discovery Cove. What would someone suggest for a youngish (27) guy who wants to have fun and enjoy the three parks in terms of what passes and what to do. I've done the Disney Thing, but not USF/IOA and Seaworld, so that I know I want to do--how much time to I need and will I have fun being alone while there? Are the line waits long or short this time of year? I am having trouble finding this info. Thank you so much for your input!
