Welcome to our forum.
My wife and I just bought an Envoy. Our dealer had both the Envoy and Aria filled. We started in the Envoy and then went to the Aria. The Aria felt noticeably smaller, which is something we would not have known without sitting in it. I would push for them to fill both tubs so you can get a feel for them.
Thank you all, I will turn off my "I'm suspicious " radar; but I think I will sit in the Aria dry to get a feel for it...I am a larger guy.Things I am looking at, and in no particular order: quality product, good product history, good customer service and of course a good hydro-therapudic experience.
