I got this from the Travel Zoo website:

"The 4-Diamond Eldorado Hotel & Spa in Santa Fe just reduced rates during the popular summer season to $149 per night (regularly $229).

You can travel between Sunday-Thursday between July 11 and September 8. Weekends are just $50 more. The world-renowned Santa Fe Opera is in season during this time. And at 7000 feet, Santa Fe is usually cooler than other desert destinations. All in all, this is one of the best times of the year to visit New Mexico.

The Eldorado is just one block from Santa Fe's historic Plaza. Its Old House Restaurant was named by Travel and Leisure as their top choice for fine dining. The hotel also has the full-service Nidah Spa on site, a rooftop pool, fully-equipped fitness center and sauna."
