Most likely Pasadena would be your best bet.After shooting all day, you will appreciate the comfort of a 4-5 star hotel
Most are only 2 Star motels. One of the nicer ones is the Best Western Best Western Plus Route 66 Glendora Inn 625 E Route 66, Glendora, CA, US, 91740
The closest would be before you start up into the national forest in Azusa, Glendora, Montrose, Covina or West Covina. Burro Canyon is something like 11 miles up the hill.
