Flats in Grassy Key

"Unauthorized charge after checkout! Proceed with caution. I stayed at Banana Bay from Feb 19–22. At check‑in, I was informed of a resort and parking fee totaling approximately $225, which I authorized as a temporary hold on my debit card. I had a trouble‑free stay, left the room in good condition, and checked out normally with a friendly goodbye from staff. However, hours after checkout, Banana Bay increased the charge on my card to over $1,000, without my authorization. Combined with the prepaid stay, this brought the total cost to approximately $2,150 for three nights in a standard room. I immediately contacted the hotel through multiple channels to resolve this, but received no response. The money was taken from my account the next day despite never authorizing this amount. This experience was extremely distressing and unacceptable. Until this issue is resolved, I cannot recommend staying here. Travelers should be very cautious, especially when using a debit card."
