The buses to and from the parks make a circuit of all bus stops. Sometimes they will do both the one stop at POFQ and all POR stops, sometimes,when busy, there will be separate buses for POR and POFQ.
We did value and then tried CBR and now POR which we visited earlier in the year. You will like it. The value's are great, but here at PO you have hot tubs, which I like after a long day walking, very nice pools with water slides, gorgeous grounds, and nice rooms. Note that although you book POR separately from POFQ, you may use all the facilities at both, including the pools. Make sure you check out the first post in this thread and Andre's website

There has been much discussion about the bus service. It depends on when you go, how crowded it is, etc. Some people report no problems, others report having to wait at some bus stops because the buses are full from the prior stop. I don't think it is terrible, just give yourself enough time, and if you want to be close to the main building and bus stop reserve a preferred room.
