You can walk between the two resorts - it takes about 15-20 mins or you can take the boat which takes about 5 mins.
I saw your other post about boat to DTD also.
There is a free pontoon type boat ride from POR and POFQ that goes to DTD/ It takes about 20 mins and is a very enjoyable ride. It is free.
You can rent boats at POR but I believe they are for 1/2 - 1 hour at a time. I am unsure if you can take those boats to DTD.
We stayed at POFQ and thought it was beautiful, but we saw POR by boat and bus and thought it looked beautiful also. It is a lot bigger than POFQ.
