We're cruising with Disney for the 1st time in March and are taking our 10 month old daughter with us. We're debating about taking a 4 hour snorkeling excursion in St. Thomas and leaving Lillian at Flounders during that time. What happens if there is an emergency with her at Flounders? How would they notify us and get us back to the ship? I'm quite nervous about leaving her for so long without being in closer contact to the nursery. Thanks!
