If you are inspired to also see many of the Wonders of the World, I would highly recommend as a first trip going to the Yucatan Penisula of Mexico to see Chichen Itza. It is easy to to travel to Cancun as Edelweiss for example have direct flights and there are some AMAZING hotels along the Riveria Maya. It is an easy daytrip from the beaches to the UNESCO site and when we visited in April it was not crowded with tourists and the weather was warm (not humid and unbearable which is charcteristic of the summers!). My only tip is don’t drink the water (which I didn’t) but I forgot to not eat any fruit which might have been washed with the local water when we went to a local restaurant on our day trip out – and so I was man-down for 24 hours! Otherwise, it really was wonderful!
