@Mor - I don't know if taking these kinds of travel vacation packages really count as that kind of travel though. I've been on a couple and they tend to be very sanitized. In fact you might as well stay home in some cases, because they really don't let you do anything by yourself or discover anything off the beaten path.
I think they can be a good introduction to a new place, but I also think that people should think outside the box when they are traveling and try to experience the place from a local point of view. This is particularly true of cruise passengers. They can spend a month long vacation without ever stepping foot on foreign soil or tasting foreign food, but they would still claim to have visited the place. I just don't think it should count as real travel.
