Yes, we've used them 4 times now and no complaints.
I think it took about 45 minutes to get to our hotel (HOJO most recently) after we got onto the bus. That was on a Monday evening around 6pm.
There are buses scheduled hourly for departures to LAX. We had an international flight, so we had to leave for LAX way early (I think about 4 hours before our flight just to be safe).
