Stayed in this place a long time ago. I don't recall having to pay for loo rolls, but perhaps they only provide a couple and then you have to provide your own.
They had a strange system in place for payment for drinks, bar etc call a TOM, electronic bracelet. It was a total pain, I hated it.
Place itself is well situated, just behind the beach, 2 decent pools and loads of sunlongers.
Enjoy yourself, I just returned from Bitez 2 weeks ago and it is very expensive this year along the front, so take plenty of cash.
