Welcome to our forum.
With company you tend to want to stay in longer, I would go to 102. 104, is great, but after 20 minutes, you will probably want to be getting out.
You are correct. I had company over, set it to around 102 and it was PERFECT.We were in longer than normal, and we really enjoyed it.
106 for me in the winter.
My tub doesn't get that hot, I believe 104 is the MAX.What kind of tub do you have?
