I'm not sure how far down International Drive that is, but last year our taxi rides were $14 each way to Sea World (I think Holy Land is near there?) and $5 to Wetn'Wild. You could always buy Intern.Drive trolley passes for a couple of bucks each for an all-day pass) right at the RPR concierge deskin the lobby--they'll give you a stop map w/listings of a lot of stuff that's along the route. Catch a taxi (there's always one waiting in front of RPR check-in) and get dropped off across the street from Wet n'Wild (about $5) and catch the trolley. Do the same thing for the trip back to RPR....except you'll have to call for a taxi, so take the number w/you.
