NYE traffic

[momtotwinglesx4]

Our family will be staying off-site at Wyndham Palms resort on NYE. We have dinner PS at 'Ohana. The plan is to watch the MK fireworks from the Poly then head back to the villa to put the little kids to bed. We'll have our own vehicle and I'm wondering if it's worth it to try to go back out w/ dh after the little ones are in bed (dd15 would stay with them), or if it will be a nightmare trying to get anywhere. Was thinking of DTD or PI or possibly EPCOT. Can any NYE veterans describe the traffic around WDW that night?

TIA,

Sue
