April 2015 - 5 Night Western Caribbean (Ft. Lauderdale Roundtrip) Cruise on Liberty of the Seas
This was a fantastic cruise. The ship was large enough to offer entertainment options but not too big that my 9 and 12 year old couldn't have a little freedom. Loved the entertainment and staff. Belize is a newer port and will improve as the years go on. Took the Lamanai River cruise. The kids LOVED the speed boat ride through the river and climbing the temples. Went to Playa Del Carmen and Xel-Ha in Cozumel. All inclusive and a whole day's worth of fun. The ice show and Saturday Night Fever were both great nighttime entertainment.
Overall... 5 days is the perfect amount of time for a first time cruise with kids.
One drawback- Our stateroom 3568 was across from the service area and the constant thumping and slamming of doors on the last night to load all the luggage kept most of us awake for a huge part of the night.
