I had my wedding here, and I can tell you the staff is second to none. Nino (who organizes everything) was so accomodating. I used the back veranda to have my ceremony too. The scenery is beautiful, and the whole environment is very comfortable. I would recomend the River Crest highly. Just make sure you are the first to have your wedding on the terrace if there are two that day. That way, you get the whole morning to set up, and you don't have to wait for another party to tear down.
PROS: Very accomodating
CONS: I wish there hadn't been another wedding that morning.
