Hm I don’t think there is a 100% guaranteed safe way of transportation. How does the Uni (I presume because of dormitory) handle parcels? If they hold onto them for a while you can sent it there.

I would also consider bringing maybe only the bare minimum / only those who appear to be least likely to break (fewest small things that stand out like spears, flags, long thing weapons etc.)

You can also just buy a whole army there :X would provide excellent procrastination opportunities.
