Pebble is not for the faint of heart.
first off in order to make a tee time in advance you must stay at one of the hotels which is about $900 a night. Now I go nearly every summer with my family and rent a house and since I am a single I have never had an issue getting a tee time the day before but if you’re going as a group then you need to stay at one of the hotels. To play PB it will cost $500+ depends on Cart, caddy, etc.
the other PB courses you can book ahead of time even if you’re not staying (spyglass and Spanish bay) and the if you’re looking for less expensive options there are several in the area. Delmonte which is the first PB owned course is an option which is an OK course, I play Poppy Hills a lot in the afternoon when the rates go down, there are dozen others within 20 minutes to play and if you have time I suggest taking a drive and playing Pasa Tiempo.
good luck.
