Thank you all for your comments, they answered my concerns :)

After 18 years I find myself going on NCL again (Pearl). I've never had a drink package before and the gratuities are included, but do people normally tip extra per drink when served or just go with the 20% already included? Second question, if I decide to take the internet package a couple days into the cruise, do they pro-rate the price based on how many days are left? Thank you in advance!
