Roaming the multiverse, there is a hotel.
At first it looks like any other hotel (or similar concept - room, board, maybe some entertainment) you might expect in your location.
The staff on the check in desk are consummately professional, and the pricing is extremely reasonable. If paying would be a hardship, they may even offer you the first night free, and you may find that turns into a second free night and a third and indeed staying as long as you like.
There are always available rooms and they're always surprisingly nice - not to the level of inducing culture shock, not yet.
If you go to any of the communal facilities - the buffet is not just for breakfast, and is always open and always included. The gym or bar or swimming pool or whatever you expect a nice hotel to have available is clean and high quality. And there may be other people there.
At first, the people you meet are who you might expect to meet, although if you talk to them for long you might begin to realise they are not all from your world, they may be from places just subtly different.
As long as you react well to this - not overtly terrified, not too impolite to coexist - your stay will get progressively better and progressively stranger. You will find new facilities, meet new kinds of people, get upgraded to fancier rooms with technology you didn't previously recognise.
Of course, you can check out any time. It's impolite to take the fixtures and fittings with you and you might find they don't work so well removed from the room and facilities, but things you have learned and that other residents have given you are not confiscated.
