Play tees that are shorter than you are inclined to. The course is at sea level and plays long.
It is gorgeous, tough, but fair, listen to your caddie, don't feed the deer, and don't stress out, just enjoy the beauty and the course. Great experience.
FYI, most of the caddies I talked to when I played there said it was a better course than Pebble...I don't necessarily agree...but there aren't any bad holes at Spyglass, every hole is a good hole. Pebble has GREAT holes and average to boring holes.
