I get the impression that the well furnished Ayahuasca tourist experience has not been the predominant one for very long. I have met a great number of people who stayed in very rustic conditions to endure their Ayahuasca experience.
I did it with my wife about 3 times, in the US. One in a very nice yoga retreat place and twice in a cozy home. It was OK. I thought the evolution and music were interesting and soothing, but honestly, the thing that turns me off is the overly sweet nature of participants. My humor is a bit dark and sarcastic and I just felt like I couldn't be myself or I'd ruin someone else's experience, which is not what I want(ed) to do. I'm pretty sure I'm done with ayahuasca. However, give me mushrooms once a year or so and that's enough of a mind opener for me... and no vomiting (yes, I know it's part of 'the work', but it's just gross to me)
Personally I do not believe vomiting to be part of the trip, it is a side-effect that could completely distract you.
If you feel nauseated from mushrooms, you may try psilacetin instead. It is shrooms without the shroom matter, available (not sure if still is, used to be) in a small-ish tablet form.
We slept outside under the stars. It wasn't for tourists, it was part of an actual religious ceremony. I didn't speak the language so I didn't get a lot out of the actual ceremony.
But I believe the experience on the drug would translate nicely if you were being pampered. You're going to confront every demon you've ever had, so being comfy might be nice.
