They get a C grade. 6 tubs on the Voyager of the seas. All round ones with basic jets and air bubbles. 2 tubs seat around 12-15 people and the others seat 9-10. The bad part was only one was above 100 degrees and they shut that one down every night! They keep one tub running all night and either close the rest or drain them each day. A couple of cool nights with a strong wind was a chilling experience.
Still we had a great time, more details to follow as I'm on about 3 hours rest. I see the world hasn't come to an end while I was gone. I did meet a couple who have a 10 year old Thermospa, I invited them here to tell us about it.
I didn't get to meet Captain Janeway or Seven
