Disney cruises are great! We've taken 6 already and have 4 more booked! If your 3 year olds are potty trained, the Oceaneer's Club is excellent and we loved it when our kids were old enough to start using it, since we finally got a chance to explore more of the adult offerings on the ship. Under 3 or not quite potty trained can go to the Nursery, which is an additional per hour charge, but still great.
I'm always happy to recommend my travel agent, Tracy Whipple ([email protected]), and she has assisted several others from this board as well.
Disney currently has west coast sailings available on the Disney Wonder to the Mexican Riviera, Alaska, Hawaii, and the west coast in general, through early December 2012. We're still awaiting the announcement of the plans for December 2012 and onward, which should be coming out shortly ("after the first of the year" was the last expectation given!)
Disney had offered a lot of kids sail free offers for the Jan - March Mexican Riv. cruises, along with Southern California resident discounts, but most of those offers seem to have expired at the moment. That also results in ships that may have reached their capacity on kids, or on rooms that sleep 4, since the kids free offer tends to increase the number of kids per room. Even so, the MR cruises are relatively cheap. I just looked and you could sail this Sunday on a 7nt cruise in a verandah room for under $4k, and on 1/22 for $4600 in a Family verandah room. 2/12 has Oceanview rooms for $3200. March 4 is the cheapest available since there is an inside room for just under $3000 (we prefer oceanview rooms, but I've heard the inside rooms are great if your kids still nap!)
We've done the parks (WDW, not DL) before and after cruises, and I prefer to do them before since the cruise is more relaxing. But if you are really looking for a relaxing vacation, I'd skip the parks at that age since they may be too short for many rides, and the lines for characters are much shorter and more manageable on the ship. Plus the 7nt cruise includes a free character breakfast, and awesome kid-friendly Disney musicals that are just under an hour.
Let me know if you have any specific questions. Always glad to help share my obsession!
