Party time at the Piers. These two (2) Gold Passports to the Chelsea Piers Sports and Entertainment Complex offer you and a guest the chance to make up in a single day for all the lounging around you did this winter. You can use the Health Club (if you're 16 or older), the Golf Club, the ice rink (with free skate rental!), the toddler adventure center (if you're 5 or under), the batting cage, and you get free, but odd-looking, shoes if you bowl. You'll never fit it all in in just one day, but think of the fun you and your guest will have fun trying.
