We usually save a few hundred by doing it this was as opposed to purchasing everything separately. They usually throw in a few perks as well. Last time they gave us a room upgrade at no charge. We will be going back in Summer 2012 for an 8 day stay at the Hard Rock.
I think we may do a 2 park VIP tour this time, although I probably know more trivia and facts about the parks than some of the tour guides.... :)
Booking flights today, will pay off room before arriving, and will buy park tickets next month. I love having everything paid for in advance, but we drug big time this year.
Short of a time table, I have dinner, lunch, shows, hours, locations etc planned ahead. But it's almost a hobby to me.
