This summer I'll be returning to the Yucatan, this time with my son, for 2010's "marquee vacation". When I went 2 years ago I took a day trip from Cancun to Chichen Itza; unfortunately, given the travel distance and the 4 stops, we only got to spend 3 hrs at Chichen Itza. That is not enough time. For this trip I'm considering renting a car for a day and driving there, allowing us to keep our own schedule.
I'm tentatively planning a trip to Iceland in Summer 2011. Instead, though, I may seriously consider this opportunity--teaching English to schoolchildren and hotel employees for 2 weeks in exchange for free housing near Chichen Itza.
