Hi debit34,
We just came back Friday from the poly and we came back in Dec from GF. We also have another trip booked for this Dec for GF and I just thought I would come on and give my opinion on both resorts and Convince you to stay at GF lol
This was our first time staying at the Poly and we loved it however we feel that GF is definitely our favorite Resort it was our first time staying at GF last Dec and it is Definitely worth the extra $$$ It is just wonderful there we stayed for two weeks and my Mom, Sister and I were definitely on the verge of crying when we had to leave lol (but doesn't everyone when they have to leave Disney? lol)
The Service is wonderful the Cm's practically trip over each other to help you with what ever you need. The service is wonderful at the Poly as well but you just can't beat the GF on quality of service! It was my 18th birthday trip and my sister's 16th and we felt like royalty they just make you feel so special at the GF like you are the most important guests staying there!
It is Beautiful at Christmas walking through the lobby at night going back to your room you can smell the gingerbread yummy
Have I convinced you yet? lol
Another thing we noticed is that the rooms at the poly and GF are the same size but, The beds at the GF are more comfortable and the room is so bright and cheerful!
Hope this helped=)
I agree with the others on the fact that you may regret it if you don't book the GF and like seaspray said you did say "convince me" so sounds like you really wanna stay!
I know that there is a price difference but once you come back from your relaxing trip at GF you will be so glad you paid the extra$$ I know my parents were glad they did!
I hope you are happy with which ever on you choose and Have a Magical Vacation
