We are looking at taking our very first cruise. Not sure which one we would pick yet. We are on a tight budget and like to pay cash for our vacations. So what I need to know is what is covered with the initial cost of the cruise- room, food, drinks, activities? What things are extra? If my children attended one of the kids clubs what is the cost? Where do you find a list of all the extra activities you can book? And when do you need to reserve your spot?
