I think that getting massages are nice and a really hot jacuzzi is relaxing, but I've been to some spas that are incredibly boring. One can only spend so much time in the sauna (literally, for one's health) and also one can only spend so much time in the Jacuzzi before it gets dangerous and boring. So, I think that spa vacations are nice if they are a part of a vacation that is fun and interesting. I like to be outside and usually spas are inside. I think that spending one full day or a half a day at the spa is nice, but more than that, I just feel like I'm being overly lazy, and I get bored.
