Nann, the Epic also has a western route. They go to Belize, Roatan, Cozumel, and Costa Maya. The Epic is a fabulous ship and so is the Freedom. Both ships will keep your children busy. I personally LOVED the water slides on the Epic. I watched them climb the rock wall. The Blue Man Group was a fabulous show. If your children don't want to go, let me know. I'd be happy to go
Seriously, though, either cruise line will be a wonderful experience for them.
