I am in the same boat as you, just a few days later. I was going to book Tensing Pen, but they are completely full. It's either Citronella or the beach for me. For alone time I would give Citronella the nod. Hettie and Chad's report offers up some info on Citronella. I like the fact that they only have a few rooms and they are spread out, so again the alone time that you really want would in my eyes be found at Citronella. You guys can be social the rest of your trip, use these two days to stayed wrapped up in each others arms.
