I've been a member now for approx. 2 years at the m'ship level where I do not have to pay an entrance fee (Thank you Amex Centurion), and have also tried different other lounges. The PP- facilities in general are not the the most lavish around, both when it comes to facilities and food/drinks, but the staff seems eager to please.
In Europe a lot of the clubs are the same ones provided by DC, so do look this up before you sign up for PP!
