From what you say it seems as though she is the dominant person in deciding where and what you all do. That is partly also of course down to the rest of you accepting and going along with her version. The more you have done that the more she has felt she has the right to do so. Personally I have done holidays on my own and with my husband and with friends. I am now a widow and resent forking out a fortune for a single room etc. So my way was to talk to a neighbour, who was also on her own, and suggest as we both wanted to go to Barcelona we might share a room. But I did set out what I thought would work. That we could share a room, thus getting a better room at a cheaper price, but that we were not committed to sharing any time together, but do our own thing and not feel we had to share anything, while of course being happy to share something we both agreed on. It was the first time I had done it and it worked well. We did our own things, which were quite different and had one lunch and a couple of coffees together. We were happy telling each other about our days and it all worked very well. I think it would be good if you and your husband sat and wrote down what sort of things you really would like to do on a holiday and see how they matched and what you might do , whether it was sharing something or even going off to do your own thing and meeting up later. You may actually surprise each other with things that you hadnt realized or thought of doing before. After all you run your own lives and chose your meals, furniture etc etc. and dont allow your friend to butt in and organise those things. Well holidays are no different. It is meant to be a reviving cheering break from your normal routine, not trailing along doing things you dont wish to do to suit someone else. It will be sad if the friendship ends over a holiday, but you and your husband will have learnt a good lesson, not to allow anyone else to organise your lives and overule your own choices, and to look forward and think about what you would enjoy doing and making your own plans, not just drift into doing something you havent chosen for yourselves. It may turn out to be a good thing, sending you in a different direction, with or without these friends. Certainly I would not feel in the least guilty about choosing my own trips but I do think that it would have been better, and easier in the long run to tell them straight away and not let it look like a secret or done to specifically upset them. Dont think I would be choosing to travel with them again unless a simple weekend or couple of days.
