i went last june with my (then) 5 & 7 yr olds. we stayed in a 3BR loft condo at caribe island. it had A/C, full kitchen, pool, and cable tv (that's right, that means Nick TV), and the kids loved sleeping upstairs. altho we had 4 beds, they shared the upstairs double. so cute!
i think the hardest part with the kids is the the actual travelling. my kids liked it there. bring sunblock, hats, and their fave portable snacks.(they did not like the jungle as well, and i love it. too sweaty & buggy!)
