We have cruised with Norwegian, Carnival, Celebrity and many years ago with two now defunct lines: Dolphin and Sun. We never had a bad experience with staff or guests except for one incident on a Celebrity cruise where, when we introduced ourselves as a gay couple, the other diners at our table awkwardly changed the topic and next evening never showed up. On inquiry, our waiter told us they had asked to be moved to a different table for the remainder of the cruise. They were part of a church group from Kansas, and while it wasn't clear exactly why they asked to be moved, we have our suspicions. When we did see them in the public areas and especially by the pool for the rest of the cruise we always yoo hooed them, waved and smiled! It's called making lemonade out of lemons. I particularly enjoyed hopping into the thallasotherapy pool when they were in it... Never mind, we made some great friends at the FOD meetings and enjoyed all the cruises, especially Celebrity which gets my vote, despite this event, as number 1 for being gay friendly.
