I do think it is worth a play. You will be there already is the best part. I wouldn't recommend driving great distance, but I have enjoyed Equinox in my 2 or 3 plays there over the years.
I'm not exactly sure how much of Travis remains, but I think the course follows the same routing as before the Rees-ovation in the early 90s. There are definately still some classic touches to the holes, and the course is one of the most New England-scenic course in the country.
Also, after I played Ekwanok (they are adjacent), Equinox is even more representative of what is down the street than one is led to believe. The first few holes follow close to the same pattern, and the land is almost identical. There is a really cool par four on the back nine that plays uphill to a green that is fronted by a deep "kettle hole." You don't see many features like that on circa-1990 Rees courses, so some of the historical undertones most definately shine through.
