The boat ride is about 20 minutes.
You can walk (about 10 minutes) to the foodcourt at POFQ. You can also check at the boat dock - some of the boats will stop at both resorts and will drop you off. Getting back is much easier - most of the busses make the first stop at POFQ and continue on to POR. Just ask any bus driver if he/she is going to POR.
