Mexican Beach's, there are tons of them, the dollar goes a long way.
And with a bit of persistance you can get away from the main crowd pretty easily. There are a couple of islands in the Cancun area that are awesome.
White sand beaches, blue blue clear water, sun, surf and lots of Corona.

Black Hills in South Dakota, 7 miles south of deadwood there is a campground hidden away just off the road. Spent a week there some 5 years back. One of the most idyllic settings I've ever seen. Lots to see & do within a 1- 2 hour drive.
But my ussually favorite is a wild river, a good friend and a cannoe.

2 or 3 days of just kicking back, floating down a river. Watching the wildlife, the scenery endlessly change in front of me. Quiet nights around a small campfire.
These are things that bring peace to my soul. That make the better part of me sit up and take notice.
