I stayed at POR the 1st week of
free dining this year and have to say that the busses were wonderful! We never waited more than 10 minutes coming or going. Also, there is a common misconception that the busses go to POFQ before coming to POR. This was only true in the middle of the day and for drop-off. However, if you get on at the main depot at POR you may think the busses have come from POFQ but in fact they are full from all the other stops at POR.
Our room was near the West Depot and every single morning we were the 1st group picked up by the bus. We then went to the North and East depots and by the time we got to the South Depot which is by the main entrance the bus was pretty full. On the way home we stopped at POFQ, then South, West, North, East. So, if you want a seat at POR, don't get on at the main depot! (It's a trade-off really, those with the rooms closest to everything have the most crowded bus stop.)
