Like Newcombe Tennis Ranch, I have visited TBarM on several occasions for conferences, and while it still has a place in my heart, I felt that the last time I visited was a bit of a downgrade.
The food was still excellent, and the staff remarkably polite and even willing to help explain some of the history behind the founding of TBarM. But the conference facilities that I was located in was in the cabins, and I couldn't help but feel a bit of "put together quickly". The past experiences I've had would be in the 4 to 5 star range, but the last time was closer to 3 stars than 4. I think the best way to improve the rating is to refurbish the mattresses in the cabins (the ones that have bunk beds) and also clean up the restrooms a bit.
