[It's late at night, probably time for everyone to call it a day and head off to bed. Nothing too unusual. In fact, even those who usually stay up late might feel the need to get a good night of sleep today, so it'll make for a quiet night everywhere...
Only after a couple of hours, they might realize there was some movement, possibly even wake up from it if they're light sleepers. Surprise! You're not alone, if you went to sleep on your own. Or you're not with the person you were sharing with, if you were already accompanied. Hell, it might not even look like it's your bed you're sleeping in - beds all over the hotels will havechanged, to fancier ones at times, other times to smaller, more cramped ones, maybe even just sleeping bags. You could even find yourselves in one of the many locations outside, on a hammock, or a more elaborated set-up, even inside a bubble of sorts.
Whichever the switch is, you'll have to learn to embrace it for a while (or embrace your new bed partner, we don't judge here), because it'll be impossible to get away for at least some time after the change. Not only that, but the switching around isn't limited to the one night. Lasting for the weekend, the general sleepy feeling will come back again (sometimes during the day, as well) and provoke random naps from people... who might end up in a bed with other victims yet again.
At least Miracle Country worries about hurt sensibilities, so of course if your character might lean towards lighter clothing while sleeping (or none at all - again, we don't judge), the magic of the world shall provide them with cute, warm pyjamas to wear once the switch has happened. Even if it happens during the day, they wouldn't want anyone to be uncomfortable. Of course, should they find themselves ending up wearing something less appropriate, that's just their bad luck.]
