I haven't been on Celebrity since 1997 but I was in a Century Suite on that cruise. It was tiny but I loved having a butler. We just came off a Princess cruise in a Vista Suite at I'll have to say the only thing missing was a butler.
Therefore, we just booked the Penthouse Suite on the Constellation for our next cruise. My sister-in-law will be in a Royal Suite down the hall.
I've been to Labadee and you should not miss it if you have a chance to visit there. It is beautiful!
I wish Celebrity could dock at Mahagony Bay in Roatan. I understand it is owned by Carnival Corp but I loved it. I would be disappointed if I had to dock at the other dock in Roatan.
