MickyD,
I agree with Dapanz1. Besides that, you're going to the HDR your 1st night in town. Then, you're doing Arenal for 2 nights, and the Cloud Forest for another night. IMHO, after tasting the HDR your 1st night, and then leaving the next morning for your eco-tourist stuff.....you'll be chomping at the bit to get back to SJO. You probably won't want to do Jaco at all. YMMV.
Regardless, don't make too many plans ahead of time. More than likely, they'll all go to sh*t as soon as you arrive. Go to the HDR your 1st night, then do the next 3 nights out of town. Then, at that point, decide what to do for the rest of your trip. I got a feelin that I can guess where you'll be for your final 4 nights !!!!!!
Have a great time.
Mucho Gusto
