Okay, does anybody have any thoughts about using the ships excursions vs booking your own excursions online? Has anyone booked their own? Good or bad idea. Are the ships excursions very crowded? I'll be in Nassau mid January. I wonder how crowded the ship will be. If you have booked your own, what company have you used? I'm specifically looking for good snorkeling. I'm just afraid that I'll lose my money if using a less than reputable company! If I do decide to book with Carnival I'm assuming that doing it ahead of time is the best way to do it. any input would be wonderful!!!!
