Have'nt cruised in over 10 years, since we had kids, so I really want them to have a great time. Our family is going on the Spirit in Oct. The Dolphin excur. looks like great fun for the kids (4 and 8 both great swimmers) interested to know if anyone has done this specific encounter.I found the web site of the facility, could book directly or through Carnival. Also there are a few different choices. One for ages 4-7 and one for 8 and up. Would it be too time consuming to do 2 separate encounters for each child. My son would really like the more advanced one.
