Hi Sheri, It depends on what you like. In Mexico some of the ruins are bigger than the ones you see here in Belize given the time you have from the cruise ships. But as one lady said once that it depends a lot on the guide you get. She said and i quote "The ruins may be bigger in Mexico but the information I got from our guide in Belize made it much better and we learned a lot more about the mayans than we did in Mexico. So there you have it, it really depends on what you want.
If you need more information on this please feel free to contact me at firstname.lastname@example.org
and I will be more than happy to oblige.
thank you, Nacho
