I saw this earlier but I got distracted, I would have responded sooner.
I wouldn’t worry too much about it, you don’t have a meet coming up and the trip is only a few days. If there are machines you could use those, otherwise just do some bodybuilding-style workouts with what is available. You can do goblet squats or just squat holding the dumbbells at your side, dumbbell bench press, rows, single leg or split stance RDLs, and so on. Who knows, maybe the equipment won’t be as bad as you expect but even if it is you can still do something. Either way, you came back from your ski trip OK and that’s worse than a relaxed trip out of town with some light training.
If you aren’t feeling too fatigued right now you can keep going for a couple more weeks and use the week of your trip as a deload.
How are your squat and deadlift feeling in terms of technique? I see you mentioned rounding your back of RDLs, don’t do that. If you can’t maintain a neutral spine then stop the set. Post some videos so I can see what is going on.
