I'm not going to LTT. You are correct, it is sponsored by Stouffer and I've read mixed reviews. Mostly good, however. They say the mac&cheese is great! (Which is a fabulous thing in my book!)
Here's what the Disney website says:
Liberate your appetite! Show your "Character" by joining Minnie and her friends dressed in their finest Revolutionary War-era garb as you band together for a revolutionary dinner feast. Your Mouse hostess invites you to enjoy a hearty American meal of roasted turkey, marinated flank steak and other colonial favorites with all the trimmings.
Minnie in Revolutionary War-era garb sounds adorable!
Food by Stouffer does not sound so adorable.
As far as Poly goes-
O'Hana- It's been a family favorite of ours for about 15 years. This will be the first time DH will ever go and I haven't been in several years (actually, as an adult), so the jury is out on this one food-wise. If you have kids I would suggest it, because I remember they did lots of fun things that we liked. (Hula hoop contest, coconut broom races, on my 16th birthday they gave me a tiara and paraded me around the place, while I waved like Mrs. America.

)
Kona- This place get's wonderful reviews. It seems to be very popular. The tonga toast (their version of french toast) sounds to die for. Dinner also sounds great!
Sorry if I gave too much info...... I'm quite a talker. (Especially about things Disney.
