My husband and I took a cruise last March to the Western Caribbean on the Freedom of the Seas. I've also traveled on the Explorer of the Seas. We are looking to go on a Southern Caribbean cruise at the end of this year and can't decide on the ship. We have loved Royal Caribbean but the Celebrity itinerary is great. We are both 24 years old and have heard the the Celebrity Summit caters to more of an older crowd. We love the Royal Caribbean ships and are a little nervous to stray from the familiar. Does any one have any advice or recommendations either way? I would appreciate the feedback!
