A float plane over Misty Fjords in Alaska followed by Champagne and crab is one of a new collection of private tours from Royal Caribbean International.
The tours break with the one-size-fits-all days way of seeing places and allow passengers to tailor trips to their interests.
Other suggestions include yachting off Dubrovnik and sighteeing around Rostock in a vintage car. Prices vary; a $100 deposit will be required at the time of booking.
