Guatemala-Mexico honeymoon

Deciding where to go on a honeymoon is no easy task, especially for two people who have never been overseas before!!! Besides, June doesn't seem to be the ideal month for going to various places... Anyway, considering that we had only 2 weeks available (3 in total of leave, but it isn't so easy to find Sunday or Monday departures!!! and on top of that exactly 3 weeks after us some friends of ours were getting married and we couldn't miss it) and that our idea of a holiday is tour+sea, we chose Guatemala for the tour (a country not yet ruined by mass tourism) and nearby Mexico for the sea.
