Cruises are actually a lot cheaper then u think, and especially if u book WAAAAY in advance.
I was on the 2nd biggest ship ever, and I knew some folks that paid 250 for the whole trip. For 7 days. Drinks and food is included. Not alcohol. The workers are all great and there's a SHIT ton of things to do. I usually go on vaca wit my fam n they don't really do much so I was always out every night just fuckin around, drunk, n doin somethin. Either drink at the 37637262 bars they got on the ship, gamble(lost way too much money but hey u pay for the expierence). They have shows every night at 10 pm. They got arcades, movie theater, buffet 24/7, shopping, golfing, and they even got a fuckin barbershop there. The point is, I was there for a week n I didn't even do HALF of the activities cuz there was just so much shit to do.
