I did one late in January and would LOVE to do another. I have asked directly but got no answer concerning rotation. The training was recorded a few years ago so I am not sure if that part is up to date.
Anyhow, very easy, not too time consuming and I had lots of free time. I was very nervous about the recording. I took someone's advice from the forum to do a back up recording. I was able to use the back up for the report, to jog my memmory on details. The recording device must be returned within a day but you have much more time to complete the report. There were hotel type observations asking about pool, exercise room, etc. All in all worth the time and effort.
They have shops designated for owners. From the training it sounded like you were administratively made an owner for shop purposes. When I reached out it sounded like you needed to be a real owner.
You get to keep additional incentives. I was pleasantly surprised to get a Visa gift card worth twice the fee.
No nitpicking on report editing and pay was faster than I expected.
