Hi! I have never rent a car at home, I don't know, but I think, you can do it in Bratislava or Poprad. Use Google. The best way to go to Poland after visiting High Tatras is to cross the borders is the peak of Rysy, it's a trekking route through a 2500 m sea level peak, you can sleep at Chata pod Rysmi 2250m sea level mountain house and the next mornig to climb the Rysy peak, then down to Polish Morrkie Oko area. If you want to go there by car, or bus, cross the border at Lysa Polana and visit Zakopane, a very lovely mountain city. Don't miss sernik - Polish cottage pie, or Goral home made cheese. You can get it in every corner. Polish beer is good, you will enjoy with zubrowka wodka :-) but take care. Nice trip!

So sorry Dylan for such a late response, I am not very good with these sorts of sites and wasn't aware of your question until now, so if this too late very sorry. But by November they would normally have plenty of snow by then, so not easy, you are not able to camp at anytime anywhere in the Tatras but there are various Chata's around, some of which do over some sort of accommodation, but you would have to plan in advance, apologies again for the late reply, all the best, Steve.
