120 nights on RSSC Voyager's World Cruise westbound circumnavigation in 2006. Having been a few very long cruises, I can say that anything over 30 days is no longer a vacation, it is pretty much a lifestyle. You just settle right in and don't have to work so hard at it every day. It's relaxing and fun. I do tend to get a little stir crazy about every 25 days, but there's good news. You can almost always arrange to get off the ship on a long cruise every 25 to 32 days. The ship will either do multiple days in one port or you'll have an opportunity to take a short overland trip and catch up with the ship again at another port in a few days. So, cabin fever problem is solved. I prefer long cruises to short ones. It seems like the same amount of work to pack, to travel to the ship and back and to be away from home for a 3 day or 7 day or 15 day trip as for a 60 day one.
