mourgavets rooms are better than the perelik. but you do relise that they are the same building so if you don't like the mourgavets just walk through the shops and into the perelik. mourgavets is a better hotel though.
mourgavets hotel is much nicer rooms etc but i always stay in perelik for BJ's and shorter journey home lol - was going to book mourgavets this year but force of habit i went for Perelik again.
Food is also better in Mourgavets and pool etc
