Hi, this will be my first trip to Mexico - if I actually manage to decide between all the options in time - LOL!

I consider going either in November (for thanksgiving) or in second half of december either to Cancun or Mexico City... Do you know how is weather in November/December in Cancun? My concern is that it will be too cold for the beach and than I don't see the point in going to the beach destination aka Cancun... I might be wrong. I really need some advice.

Also, if anybody can share their experience with getting good deals in Nov/Dec for Mexico, that would be great! Essentially, I don't have a good sense of what a good price is...

Thanks!
