When you are going to Poland, you don't say who you are going to see.
Simka or Kostecki?
If it's Kostecki - you will not be able to stay at hospital and your driver will drive you if you wish. If you prefer to walk, it's no issue - perhaps 15 minutes by foot if you stay at the Hotel Arena.
For the most part the nurses are wonderful with one minor exception...
Read my wife's post here for some details about her experience:

Regardless of which clinic you are going to, as the support person, you are going to be somewhat stressed out - it's normal IMHO. There will be others who feel the same way - engage them and talk about it (thanks Rach and Jan). You'll feel much, MUCH better - I did.
If the talking doesn't help - perhaps a sampling of Polish Vodka will.
(for the anti drinking crowd - please note the winks...and moderation is always apropriate)
