I do an even cheaper version of this several times a year - I call it camping
I pack bottled water, McDougall Right food cups, instant oatmeal, raisins, tea, raw veggies and rice cakes.
I find a nice state park (I did say cheap
) near athletic adventures: kayaking, lighthouses to climb, adventure parks with zip lines and canopy courses, hiking, dune climbs, remote waterfalls, etc.
I pitch my tent, turn off the phone and chill for 4-5 days.
Repeat until vacation days run out
