For $150/year, I could ship or airline check a lot of stuff back and forth IF I needed it. [/quote]

Yes, but if you bought beach items (floats, chairs pads, etc) small charcoal grill, medical necessities (c-pac machine) noise machine for sleep, etc then it's very much worth it. Heck, if I didn't go up & down then up again in weight I'd leave all my clothes there just so I'd have no baggage !
