Disney - part 2?

So I have to take a work trip in January to Orlando. I was moaning to my friend about the fact that I was going on January 16th - the day BEFORE my birthday in the year that Disney is giving away free admission on your birthday. She looks at me and points out that Jan 16 is HER birthday. So now we are looking into both going. I will have to work some on the 16th, but if we stay over til the 17th we could both go and only pay for one day. Hmmm.... Disney sans kids - sounds like fun!!
