Hilton Parsippany - Has nice lounge historically. But, new management just started with some indications of lounge cutbacks (staffing, hours, offerings) so this is a TBD. Great place to gather small (4-5 people) group if needed.

Germany
Hilton Munich City - Nice EU class lounge
Hilton Dresden - Nice EU class lounge
