Elite status on Celebrity will entitle you to one free bag of laundry. There will be a bag in your stateroom (closet most likely, but ask your stateroom attendant if you can’t find it). It’s for up to 30 items, and they will be returned washed and folded in about 2 days. You need to tally your items on the laundry slip (4 tee shirts, 2 shorts, 2 pairs socks etc.) then write Elite Free Wash and Fold on the slip. It’s a nice perk, as I can get my travel clothes freshened up for my return home.
There’s a gelato counter near Cafe Al Bacio, and you’re entitled to a free scoop once per cruise.
