We were on the Rhapsody last April. My then four year old was a little too shy to do the planned activities, unless there was someone in the playroom he knew. So it really depends on your child's personality. The children are divided into four age groups and there are planned activities throughout the day and evening. I wouldn't worry about your daughter having fun, but I do recommend she bring along some of her favorite toys, activities or games. The library offers limited numbers of board games and children's books you can check out and return at the end of the trip.
