I went back in the first part of November with the GF. She loves the place so I finally went with her after three years of begging.
1st off, it was a blast. You will have a good time.
She booked ours as some special offer and we stayed in the All Star Sports Resort which is an entry level place, got the meal package, three days of park tickets(park hopper included), four night stay, and it was $480. We spent another $200 each, eating a nice place one night, and most of mine was on booze. Research the times to go, and it's very affordable.
Two of our friends went with us and they had their 2 year old with them. He had a blast.
I had only been once when I was very young and didn't really know what to expect but my suggestions are:
-Book early and look for a special deal they will offer in the off seasons.
-$50 a day for booze per adult is a minimum
-Park hopper is a must
-Book fast passes the first day you can
-Wear your best walking shoes. We did about 9 miles a day.
-If you have the opportunity to go at the food and wine festival, do it. Had some amazing food and brews. Snack credits from the meal plan applied to the food, deserts, etc. It was an awesome deal.
