Pro- I think it is the best $35 we ever spent. Of course we use it too. We have sailed on 5 Celebrity ships including the annual reunion cruise on the Millennium last year. The perks and special upgrades and parties and special embarkation desk is well worth the one time charge per family. If you don't like cocktail parties, don't care about getting a better cabin and boarding before everyone else, then don't spend the little extra after your first Celebrity cruise.
