This just arrived in my inbox:

"Thank you for your interest in the Rockhouse. Unfortunately we are fully booked for the period you have inquired. We appreciate your inquiry and apologize that we cannot satisfy your request. Please find attached further information on the Rockhouse. We look forward to welcoming you to the Rockhouse on your next journey to Jamaica. Please advise."

(sigh) Can't believe my bad luck...
This is becoming so exhausting.
It’s just one let down after the next…
I feel like giving up…

Maybe there is some availability at the Roots Bamboo campgrounds. We can pitch a tent, rub some sticks together to start a fire, and sleep on the beach for our anniversary…

Well, I just hope others learn from my mistakes. I should not have waited until I had plane tickets in my hand to start officially booking.

Thanks everyone for all your help though
I will add Rockhouse hotel to my bucket list….
