We are looking to travel to Mexico (cancun side) this Christmas with our DD 6yo and DS 3yo. We will be meeting my DM 72 yo and my sister and her DP and DD (6 months) coming from Australia. We need to find accommodation that is suitable for children but isn't too 'package holiday' as my sister and DP don't like that sort of thing. Any suggestions for smaller family friendly hotels near Tulum or the Riviera Maya?
