Most cruises are gay friendly. I have been on probably 8 cruises & have never really felt incomfortable. Have cruised Celebrity twice & they are a much more upscale line, than say, Carnival. I did cruise Carnival once & it is a younger party straight drinking crowd. The last cruise we took was on Holland America to Alaska. I chose that line because they cater to an older crowd and I figured there would be less families with alot of children and I was correct. It was a more refined atmosphere but not alot of late night nightlife. I highly reccomend either Celebrity or Holland America. You can get some good deals on vacationstogo.com or thru alot of the cruise websites. I have had the best luck pricewise with a website called cruisecompete.com. If you know the cruise you would like to do, yougo to this site and enter the info for that particular cruise Then you will receive bids or offers from various online travel sites for that specific cruise. The prices vary greatly from bid to bid. I just give it a day or so & then book the lowest price offered as it is all for the same cruise. If you need any more info feel free to message me directly.
