Anyone else struggle dealing with step family over the holidays?

The holidays can be a stressful time and over the years I've found it more and more difficult to go down when lots of extended step family are down there. The arrangements are typically crowded and often end up sleeping on couches or a air mattress or something like that due to the amount of people in the house. It really digs in that its step family that is causing the crowding and taking up all the beds as well, as you just don't have the same familial relationship with step-anyone as you do with actual bio relationships.

I think this is kind of a shame that the holidays are this experience every time, they are often not fun and I often come away with a bad feeling about it. I've discussed this with my parent and step-parent, but nothing really changes and they get defensive about it and completely shut down at the thought of not bringing in all of these people and taking up beds.

It's gotten to the point where I don't really want to go over for the holidays anymore if they are going to be there at the same time taking up all the bedrooms (they often are), due to the crappy experience I come away with. There is so much pressure during the holidays to be with family, especially when others are doing it. If you are feeling crappy though about the experience afterward, is it really worth going?

Does anyone else with step-family experience this during the holidays? How do you deal with it? Do you skip holidays with them entirely and do your own thing?
