Considering a cruise on Summit the end of Jan or early March. One of us dives, both snorkel. It looks like there are some good shore excursions at each port centered around both diving and snorkeling. Do you feel adequate time was allowed for snorkeling and were the dive trips well run? We're looking for French Angels, Queen Angels and damsils. Approximately how many people go on the snorkeling and diving trips? Is it possible to dive or snorkel from the cruise boat in any port as they do on Raddison?
