I just came back from Panama yesterday and am soooo happy I went!!! The Decameron is an extremely large resort, with 3 lobbies, lots of pools, bars and restaurants, and STEEP stairs and driveways to walk up to the rooms (unless you book a ground level oceanview room). The grounds and property are well taken care of and nice to walk around at night, they have these enormous Corotu trees which are a sight to see, so amazing. My only complaints were the rooms, we switched from rm 2317 which was in the oldest set of buildings (10-20s) to the newer buildings (40-49) to rm 4133. Both weren't much different from one another, there was mold in the shower and wasn't very clean, had a little damp smell too which either went away or I got used to it. The staff are very nice and accommodating as well, they were all great.
I was super busy coordinating my wedding and shopping around all week, I hardly had any pool or beach time (2hrs tops!), but managed to catch the staff setting up for a 5pm wedding on Sunday Sep. 26. Here are the pics I took, sorry I didn't get better ones.
