I was there this morning (first time I’d been on a Sunday), and there were people there, but it wasn’t absolutely thronging. It wasn’t too hard to find the jacuzzi empty, for example. So I guess it depends on whether you definitely want action or whether you’re more just going for the ‘vibe’ or quiet time in the sauna or whatever. I’ve not been many times yet, and I’m still a little nervous/awkward, so I’m happy going at quieter times right now, and Sunday seems to be good for that.
