I really want to book this excursion, it looks great for my kids and all the posts I've seen says it is great BUT... we arrive in PV at 10am and leave at 3:30pm. The excursion page for DCL says this is a 7-7.5 hour excursion, but obviously, for us, the max it will be is 5.5 and probably a little less. PLUS, it takes an hour to get there and back, right? So realistically, we will be lucky to actually spend 3 hours there. And it is kind of expensive - $95 for adults and $65 for kids. I don't mind spending the money for a great excursion, but will the short amount of time ruin for us?
