POR (DxL) & POFQ are sister resorts, so you should have no trouble using the mug at either resort. I have mugs from several of the resorts I have and have not stayed in. I have one from DxL and one from PO. On my last visit to PO, I brought both mugs and never had a problem with it. On my recent trip to the Movies, I brought my old one from the Music and again, no questions & no problems. This fall I'm staying at both the Caribbean Beach (1st time) and at POFQ and plan to bring my PO mug with me to use there. People have different opinions regarding this. I have never used mugs from one resort at another (unless they were sister resorts), but always bring my old one's to use at the resort that I got them at. It saves alot of money. Another tip would be to bring a few water bottles with you. A small bottle of water at WDW costs $2.50-3.00 each. If you drink alot of water (like I do) that adds up pretty fast, so I would refill the bottle with water, then use the mug to get lemonade in the foodcourt. I asked at CM on my last trip to PO and she told me no problem using my old one. Most of the mugs are pretty much the same, since it would cost the company alot of money to change the mugs every year.
