Hello Boomama32 and welcome!
I don't know where you are staying but for the budget conscious I would recommend Disney's on-property moderate hotels like Caribbean Beach or Port Orleans. They give you some of that Disney hotel magic while still remaining very affordable.

Plus you get to use the buses to go around to all the parks when you stay on property. It's very convenient.
Money-saving tips... we've got tons of 'em here on the DIS, check out the Budget Boards.
As for really getting the most out of Disney... planning planning planning! is essential. Alot has changed since you visited at the age of 16! The way I always approach a WDW vacation is to first buy a Passporter WDW book (available at passporter.com or amazon.com or Barnes and Noble). This is an excellent book that gives you a great overview of everything in Disney World at a glance from dining to rides to accomodations. It really helps you organize your thoughts and figure out what things you really want to do. Plus it has mini-descriptions of all the restaurants which is great. (visit
www.allears.net for full restaurant menus) Then I dive in by mapping out each day (this year I did it on a spreadsheet! I know, nerdy!) and figuring out on a base level what park/parks I want to be at on that day. I don't usually figure out every ride or anything, but I do make a note of rides that are closes for rehab or parades/shows that occur at a specific time. This kind of planning really helps with focusing on what you want to get out of your trip, and organizing a group of people as well. I've met people who had NO PLAN and they were so overwhelmed they just ended up wandering from thing to thing in the parks and didn't see everything they hoped and then said that they had a unenjoyable Disney trip! And once you've done the basic plan you'll be able to find lots of deep details about all things Disney here at the disboards like reviews of rides and restaurants. Very very helpful. I have booked or not booked a restaurant based on a disboards review! Also if you are going on the
disney dining plan (or not) make sure to make your ADRs (Advanced Reservations) ahead of time for the sit down restaurants you'd like to eat at. 407-WDW-DINE. There are so many amazing restaurants at Disney. Some of my favorites are: Boma, Whispering Canyon Cafe, Ohana, Le Cellier, Jiko, Spoodles.
My final tip is... be prepared in the parks. We always travel with a backpack containing our essentials (sunblock, water, refillable mugs, hats, bandaids, etc.). I've always found the backpack system to work out really really well (although others tend to prefer being bag-free). A waterproof backpack will really help you out alot with carrying basic stuff as well as any purchases along the way, and it can squeeze onto all the rides.
Have a great trip in October! I'm leaving in 5 days!
