Venue stress

This might be just too much anxiety stuff but I'm really starting to have issues with our venue. Not even sure if just posting this for a rant, but I would also like you guys opinion on it and what you'd do?

So apart form, of course, getting married to each other, our favourite thing about our wedding is our venue, since it's going to be on a mountain. It's very popular and touristy and there's gondolas up, but they're often quite full.
When we booked them, they told us there wasn't a space for the bride to get ready, so Id have to go up all dressed up with the risk of my FH seeing me and all the attention and all that. I really want neither one of that. They themselves also offered cabins they have up there. We weren't aware of it, but you can rent them for a night or to get ready in. We first wanted the big cabin so that I and bridesmaids could get ready (we have a morning wedding so it would also save plenty of time travelling) and some other people could stay over to help early with the set up. Then they told us "Oh, sorry it actually isn't available" while they told us they don't book the cabins more than a year out (this was in February or something, our wedding is June 30th 2019), but they offered the smaller cabin again saying they still had that, sending pictures etc, put up a tentative booking for it (without me asking that, they just did that themselves) but they'd contact me a year out. They didn't, so I did it myself a couple of days before a year out. They had booked off 30 to 1, so I asked if it could be one day before that and if I was allowed to let another girl sleep there as well. Everything was great and perfectly available and they said it was all booked, just had to reconfirm the week after and pay.
Two weeks later, they haven't gotten back so I email again (last Saturday) and they've just gotten back to me saying that they regret to inform me that they won't actually rent out the cabins anymore in 2019.
This feels really weird to me since they offered them theirselves and it was also all fine just little over two weeks ago, they set up a booking and all that.
So there's now no more options to get ready at the mountain itself, I gotta get ready somewhere else and have to get all dressed up in the gondola which we rode last weekend and it was crazy busy then, which makes me really worried and uncomfortable and unhappy about everyone already seeing.
It also really worries me if I can actually trust my venue on not anything else going wrong since this comes across as really messy. But also feel like nagging bridezilla or something. And since we really love the venue we also really still like to stay there...
