We're sailing in the Roy suite 8530 on the Wonder to Alaska next month. We're really looking forward to it. I booked it opening week; perhaps the 2nd or 3rd day.
I chose the Roy because we preferred the darker wood and wanted to be on the mainland side of the ship on the way up the coast. There are a couple of youtube video walkthroughs of each suite on the classic ships that you can check out.
My sister and I are sailing with our kids DS12, DD12, and DD16. When we travel, we prefer to stay in the same 'container', but not be on top of each other. That doesn't leave much choice on a ship. We could have booked connecting cabins, but that just isn't the same.
We would like to sail on one of the new ships, but a regular 7-day Caribbean on the Fantasy during 'kid available' season is $10k more than the suite for Alaska. Man. Two 1BRs on the Fantasy would be about the same as the same as a Royal to Alaska.
So long my family doesn't get that double-hankering for the Fantasy, we're going to stay with the classic ships.
