We usually stay at either POR or POFQ and walk between the two to share pools, food, etc. if needed. However, if saving money is top priority, I can usually find a standard CSR room for less and I would not hesitate to stay there.
Most of our trips have been 7-night stays, and we usually get 7-day or 8-day park tickets based on if we have time for partial park visits on arrival and/or departure days.
