I have three trips planned for this year: 3 days, 4 days, and 6 days. I've done all the math and it looks like buying an annual pass is the thing that makes sense for me. I can't find much info on them, though. I know that sometimes there are room discounts, and it seems like I read there are some dining discounts. Where is the best source of information about them? Can you only buy them at WDW or can I get one ahead of time at The Disney Store? If I get one ahead of time and just have the voucher, can I still access the website (I think there is one...) to find out more about discounts? TIA for your help.
