I agree w/ILUVPARIS....
since we get in late to LIH we won't be doing a Costco run but will the next day... DH got hooked on their fresh fish selection, kids LOVED the poke and we always find other stuff for the 10 days stay. With a teenage boy and DD who's picky about eating out Costco really does fit our needs... but then again we've been a costco family since '89.
