7 day Cruise
Cruising is probably the best vacation value you can find. I know many people that claim that is true of "all inclusive" resorts too, but even if those worked out to be the same cost, you only go to the one desitnation. On a cruise, you can get a week vacation for a family of 4 for about $75 per person per day.
With cruising, all your entertainment, food and lodging is included. No, drinks are not included which is not the case at some all inclusives (but we are not cruising for the sole purpose of drinking.)
