Hope you can all give me some ideas... for a hen night that is

I am arranging the wedding of my niece at Paradise Cove during October 2007. One of the things I need to do is arrange an evening out (call it a hen night) for all the women attending. There will probably be about 15 of us. The men are making their own arrangements. The question is where do we go?

I fancied the idea of a spa day and a good meal in the evening but was shouted down as the others dont want to 'waste' a good day at the parks. So any ideas for some decent food and a good evening out?

Help!
