If you want towels replaced leave them in the bath in your room, one of our group brought his own towel and one used the hotels. You will not be permitted into the swimming area without flip flops but don't worry you can buy them for about £5-7 in the shop outside the pool area.
On a similar subject, does anyone know what swimming 'attire' is OK.
I went on holiday to belgium and the rules were that you had to wear 'speedos, not swimming trunks' and that everyone had to wear swimming hats.
Unsurprisingly my boyfriend was not impressed and would not go swimming.
(He went to the bar and drunk Hoegaarden instead!)
I take it there's no rules like that about swimming at the Perelik?
