well i just got an answer at SWA.
i hit POST for my question and the nice lady at SWA called back and said...
those kind of beach chairs fir in a carton/box that SWA provides.
2 of those chairs will fit in 1 carton.
each carton counts as 1 piece of checked luggage = FREE
SWA allows 2 free checked bags per passenger
Arashi Beach, Hyatt, Radisson, Shopping, Flea Market, Downtown, Palm Beach, Everything
we were thinking of bringing chairs ourselves but just wrapping rope around it so it doesn't open up and checking it. I mean people check golf bags, etc. we're still trying to find out if you can get those lounge chairs that open up, cheap ones with the plastic or whatever criss cross slits there
