Which company for Character Meal vouchers?

[mommyof2boys1girl]

I know Last Minute Travel is probably the cheapest, but I'm not sure if I can resolve any issues in time. They ask for a date on their website - do you have to go on that date? What if your plans change and you decide to go a different day?
We leave on Sunday, and will probably do 2 meals - Ariel's and Mickey's Surf's Up. I know it's cheaper to get the vouchers, but I need a company that's reliable and will e-mail the vouchers without a lot of difficulty. Any advice?

I know a lot of people recommend ARES Travel, but I've never used them and don't know if they e-mail.
