Welcome to the forum! While I haven't stayed there, I understand Sol e Luna is a nice place to stay and it definitely is a lovely place to dine!!
I might suggest though you re-think your choice of vehicles. I think that's a 4 wheel drive vehicle? You really don't need a 4 wheel drive on SXM, and the price is very high for a car like that, versus a beat up rice beater of a car, which is what most of us rent. Plus it's really hard to park that kind of a car on SXM as most parking spaces on the island are very tight.
Regardless, planning is half the fun, so enjoy the next few, long months!! <img src="http://www.traveltalkonline.com/forums/images/graemlins/Smile.gif" alt="" />
