Two years BC - that's 2006 or so years ago! Damn, I've heard of planning ahead, but that's incredible :lol:
OK - pedeantic joking aside, I'm a budget person and so stay offsite. I get good last minute deals from the UK that WAY undercut anything Disney can offer. All hotel rooms look the same when you are asleep, so don't feel you are missing out on anything.
Most of the meal vouchers you read about are left overs from someone else's package vacaction and are sold on ebay. You can take the risk if you want, but there is a chance you will end up with something totally worthless.
The only voucher available to regular guests is at the counter restaurants in Animal Kingdom - for $12 you get three vouchers, one for an entree and drink, one for an icecream or popcorn and one for a bottle of drink.
To save more money, eat at counter service, bring small snacks into the park - the time that this was banned is long over - and drink water, either brought in yourself, from the drinking fountains or when you order counter service they will give you cups of tap water for free. Just make sure you ask for tap water, or you will get Dasani.
And finally - stay out of the shops and don't take up pin collecting
