Wow if you haven't booked your December travel to CSA by now you're way behind the 8-Ball. We were there the second week of last December and the place was booked solid. That's usually the week of the Triathalon hosted at CSA. We booked in March and our friends booked in June. They had to stay in Montego Bay the first night and then meet us at CSA the second day. They could only get a Garden Suite, the lowest class of room for their stay.
As far as the weather it was awesome with 70s at night and mid 80 degrees during the day. Clouds did roll in from the West most nights and the sunsets weren't the greatest.
I wish you luck.....ENJOY!
The first weekend of December is when CSA hosts the marathon/half-marathon and it's always booked full. Not that you'd notice it. The place is huge and never feels crowded. The weather is great, mid-80s during the day, still warm at night. You'll love it. Not sure what days you'll be there, but we'll be there from the 3rd - 10th. Enjoy.
