Plans for our July trip are shaping up nicely. We've already booked a few chill out days in Puerto Morelos but would then like to go to Merida for the Sunday markets and visit Chichen Itza. We need to be back in Cancun for an early afternoon flight to Oaxaca on the Wednesday. We were originally going to get a bus to Merida and back to Cancun but might be nicer to drive back and stay somewhere on the way. Is Vallodolid worth visiting or should we stay at one of the haciendas near Chichen Itza?
