I just booked a 4 day cruise June 1st on Carnival with a window on the empress deck which is the top deck for cabins on the paradise and for a resident of California, I got a rate of only 119.00. If you want an inside cabin, it's only 109.00.
If I was to take a day trip to Catilina, it would cost 60.00 not couting food, so, basically for the same aount of money, I'm getting 4 days of food, entertainment, housing, transportation, fun and sun!
