The new guide for cruising is located on the web at dvcmember. I don't know if you need to have a member id and password to see it or not, but it varies of course by season and room size.
Category 10 ranges from 104-153 (inside deluxe stateroom). Each person is charged the points to stay in the room, so if you have 2 parents, and 2 kids, you are looking at 316-552 depending on the season.
I went on a 7-day cruise in Feb 2002 and it was the best vacation I ever had, so I would highly recommend it if you have the points. (It took me 2 1/2 years of points to get my vacation "paid" for). They will allow you to pay points for 2 guests, and then charge $$ for the other 2, if you need to, but you can't pay 1/2 points and 1/2 money for any guest. Its one or the other.
If you need to "borrow" points, I may have some for sale.
Thanks.
