Spa was excellent (see brief review here).

Great service, really good treatments and peaceful environs. Just note that the treatments do what they say - usually the whole cooling/heating thing I shrug off. We had sunburn and were advised to have the cooling scrub and wrap (followed by a massage and facial). Before the therapist had finished putting the wrap on me I was shivering and teeth chatting due to the mint. They had to put blankets on me, turn off the air-con and open the windows to the 32C heat outside and it still took 20 mins to stop shivering. Although not entirely pleasant, the treatment did really help our sunburn, so don't worry too much.

I'm sure the 6h couples package will be fantastic. In fact, I may have to look at doing that during the DO!
