If affording the Poly is a financial sacrifice for you (it would be for my family - although staying at the Poly is one of my favorite nevergonnahappen fantasies), I would suggest visiting a moderate resort this time around (POFQ for convenience, or CBR if you want a "quasi-Poly lite" theme but a less convenient resort), and making a dining reservation at the Poly during your visit, after which you can walk around the resort, check out its amenities, and see if you think it would be worth investing in for your next Disney trip. Or, if it works with your budget, consider resort-hopping to the Poly for the last night or two of a trip.
