Should I try to book my shore excursions before sailing on the Voyager World Cruise? I would like to go to Xian to see the terra cotta warriors and know it can be pre-booked. Also is it worth the trip to Ankor Wat? Or would it be more fun to do the Orient Express? Or both! I assuming the regular excursions can be decided on board. I know a lot of you set up your own tours so am open to suggestions. 55 ports is a lot of planning.
