Uri,
I would suggest taking a week here in Orlando (Central FL) and go see a launch. And, if they scrub, you'll have time to eventually see it during that timeframe.
And then in your spare time, I recommend going to Sea World or Universal they are much more fun than Disney World...IMO. Sea World has good rides, shows, etc and the lines are fairly short.. My .02 cents...
Overall, I'm just spoiled as I seen lots of launches (plus most of the rockets) since 1984 when I was stationed at Patrick AFB (when in the USAF) and worked KSC for 4 years ('93 - '97)... Needless to say, I haven't missed a launch in years...
Keep us informed...!
ps. You know what would be cool, is for a bunch of us "fans" to gather at KSC for a launch and all watch it together and perhaps sync it while watching "live"... Realistically, it'll probably never happen, but it'd be cool IMO.
