I had a Vegas for 3 years. We loved sitting in it etc etc but The ISSUES! (Largely leaks from tubes/ the heater/ the bubble inlet valve). Get yourself on the FB forums.
We've slightly 'upgraded' to an Intex Greywood. Not helpful, I know, given that you have a Layzspa!
But, here are the things about them:
You HAVE to stay on top of the chemistry. It's really easy to do but if you don't, you enter a whole world of problems. Don't 'leave it a day or two'. You'll always read of mavericks who got 'just jump in!' But- okay, filled with tap water. Through a hose that's been sitting out breeding legionella. And heated to 38 degrees. Soup.
Look at the Youtube videos that'll explain the importance of correct pH. That's key.
If you have hordes of kids in and out of it, SHOCK it often. Don't encourage or even allow head-dunking.
We don't shower etc before going in; but it's me and DH so we're reasonably clean!
Insulate, insulate, insulate. It costs!
I love my inflatable hot tub: I use it 7 nights a week, but even though we're pretty experienced. I check the chemistry at least once a week. Usually needs pH plus.
Enjoy.
