My husband and I are going on out 1st cruise in May. Everything has been pre-paid except for our drink package. I know that's expensive, but, we will get that when we get on the ship. My question is...since our gratuities were included in our package...there won't be any "surprises" will there? And as I understand, the food is free unless you go to some of the speciality restaurants. I'm not sure we'll do any excursions at any of the Islands. We'll probably just walk around. Anything else you can tell me as what to expect in the way of "extra charges" ?
