I think this is a cool piece. I picked up this old room key and found that it had the dates that the travelers stayed at the hotel written on the back.
The dates were Nov 4th to 15th 1973. The Hotel was said to be closed in 1973 and became Helo Isla Flamboyan at that time. This would make a small
window to swipe the key before the hotel closed. Interesting that the people had the idea to document the dates of their stay in this way.
