Thanks for the comments folks! Yep, we've had it open for 3 days and been in it 3 times. Can't wait till the first calm snowfall. Actually tonight it is clear as a bell, so another experience is awaiting.
Yes, those are tube lights along the steps and raised tub deck ($10 for 18 feet at Home Depot). And yes, that is an above ground pool near the tub.
Best wishes...
