The Harmony of the seas is the perfect cruise for kids. I went with my nephew who is 8 years old and he had a blast.
Rock climbing wall
Theater, I watched the premiere of Trolls and Mrs Peregrine home for peculiar children
Ultimate Abyss slide
There are also water slides, kids pool with games, video arcade and a kids club that kids will enjoy and have fun.
Kids will love it and families can relax while traveling.
