i had an order of bromeliads that were in shipping for about 11 days... when they arrived they were soft and slightly curled up. what i did was immediately put them into a room temperature water soak for about 30 minutes then gently acclimated them to light after being packed away in a box for 11 days (in other words, i didn't just put them under my light source right away. I put them off to the side in bright indirect light for a few hours.)
After a few hours, the broms noticeably "perked" up as they absorbed water and began responding to the light. At this point, i put them into a 40 gallon breeder tank i use as a quarantine/grow-out plant tank, where i let them color up and regain strength for about a month, month and a half before mounting them in tanks.
I forgot to add that after the broms have soaked up their fill of water, I also do an additional step of disinfecting my plants with a mild bleach solution and dechlorinator rinse (absolutely hate nemerteans, slugs, snails), before putting in the grow out tank, but if your plants are looking as bad as you say, i might wait a little before treating with a bleach solution.
hope that helps
