Ouch. Make sure you test the LFS's water, since I know most LFS around here have water that I never go from the bag into my tank. If it's from their coral displays, then it's your best bet. If it's from the fish tanks, then see if they use copper, check salinity & nitrates especially. You might be better off seeing if any locals can board your stuff for a couple of weeks & it'll probably be cheaper & safer. I hear they'll do anything for some beer
(jk) You'll also make some useful contacts that way.
