We will be at the Belair at the same time. 1st 2 weeks, just the 2 of us, 3rd week, adult children and granddaughter, 5, (1st time to SXM).
I think 2 car rental is good idea for a group your size. Since we will only be 5, we can get by with 1.
Maybe we can compare notes on what you decided on the beach or @ Monday night get together.
We have been going to Belair for a long time. Feel free to PM if we can help in any way.
