I am looking to go on vacation with the girlfriend for 4-5 days next month. I am looking at Mazatlan and Puerto Vallarta - they are comparably priced and both seem to be pretty good places to go. I am looking more for a relaxing vacation - not really interested in getting wild and crazy. Anybody have any input? On a side note, I have about a $1,500 for transportation/lodging for 5 days/4 nights. Anybody have any other alternative ideas?
