Hotel Greif
Brass disc fob, room 81
A key from the decade you were born, married or are celebrating. Only keys with an era in the listing are placed here, so nothing is guessed.
Enter the year of the birth, wedding or hotel stay.
Anniversary math for this year: a couple married in 1976 reaches their 50th in 2026, and a couple married in 1966 their 60th. Next year, 1977 and 1967. For other years, subtract your anniversary from the year it falls in.
