I would stay onsite at one the All-Star Resorts :
All-Star Sports
All-Star Music
All-Star Movies
Pop Century
These hotels is value price resorts that anywhere 109.00 being prefered being close to the food court and the pool. But if live without being close to the pool and the food court thatn about 10.00 cheaper. 99.00 a night.
I happend to think the All-Star Resorts is the best value. If was not for the All-Star Resorts I would be force to stay offsite.
Offsite accoumdations is cheaper than onsite and can be a good value because some hotels include breakfeast that save meals right there.
If do decide to go offsite be sure check Orlando Attractins and Hotel board on this site. That's where all the offsite people hang out.
A place to check for hotel reviews is:
tripadvsior.com
travelocity.com
biddingfortravel.com .
Do not let some tell that must stay moderate or delexe to get the WDW experince. Go with what you can afford and what your family likes. Some say the value resorts is small for a family of four. I think just a the perfect size. The food court is reasonable and have kid friendly food.
Tickets
ticketmania.com is good deal is reliable legal
Alamo.com has good deals to
Disney Store they tickets at the store
Food
You can save money by bring food with you for hotel room.
Some things I bring with is:
bottle water
drinks
peanuts
potato chips
ceral bars for breakfeast
I am one the few people that is does like alot park food. That's only because I get fill nachos, popcorn, hot dogs and candy doing baseball seaon for free.
Only about two buy in the park is cotton candy and snow cone that may weakness.
I would try make a PS for food place. If can't go offsite Thanksgiving dinner because it will probaly be easier to seating quicker.
Meals is cheaper offsite. Pick up the tourist books at the welcome center they have all kinds of coupons for restaurunts.
Driving or fly
Driving is cheaper and givings option going offsite for meals
Sounviers
I would not sounviers in the park or at the hotel. Go to offsite to buy cheap T-shirts 4 for 10.00 dollars places. Better yet go to the Wal-mart for t-shirts they is reasonable.
I hope that helps to get you start.
