One last piece of advice is that it is MUCH easier to circumnavigate the world in a westerly direction than an easterly one! Our 2 month cruise was half-way around the world and flying the rest of the way, it was all eastbound. It was tough! You lose an hour every 3 days or so on average. Traveling westbound you gain hours. So, instead of losing an hour of sleep every couple of days, you get an extra hour of sleep! (Of course, when you cross the international date line you give back all those hours plus some, but at that point it just feels like a regular time change!) Now, you might think it won't matter and that you can lose an hour of sleep every few days, but remember that it isn't just you. The crew also lose that hour of sleep and it is hard on them and you will notice it. The word on this year's Voyager's WC is that since the 2007 WC will go east to Asia and then turn around and come back west and that they were going to change the time change point from 2am to 2pm. That way the passengers and crew would not lose sleep, but hours from the afternoons. Just something else to think about. If you have a choice, westbound is much better than eastbound if you are doing a circumnavigation. Of course, you may not have a choice. It is possible that all the lines doing World Cruises in 2009 could be traveling in the same direction, or like Voyager's World Cruise in 2007 not actually make a circumnavigation but go half-way in one direction and then turn around and come back. That's all I can think of for now. Let me know if you have any specific questions.
