Has anyone here ever been? I've booked a surprise weekend trip for the H2B for his birthday in September with 4 of our friends. H2B has been before but I never have. I'd like to keep it a suprise for as long as possible, but am wondering about booking activities. Think I should try and book a bunch in advance, or can we just turn up and do them? Also, do you have to pay as soon as you book them, or could I reserve us places and then cancel if he decides he doesn't want to do one? Thanks!
