Thanks for all of your replies...what you all have said makes total sense...except we won a free week at an offisite resort...nothing else...just the room for a week and are going to Disney 3-4 days on our own...would rather stay on site, but didn't work out that way this trip...like I said...just read this somewhere and thought it fit the bill for this trip...oh by the way I just called reservations and campsites don't seem to be hard to get...I could even book one during Memorial Day weekend????? For a site with just water and electric it was $55...to me still worth it to spen an extra 4 hours at the parks and w/ $10 parking knocked off...$45/day or for us $11.25/person it is worth it...and we can still enjoy the campground facilities throughout the day and evening.
Keep in mind that the hours change but, on the information guide I have from our last trip ( just a coupleof weeks ago ) morning Extra magic is one hour.
Thurs. MK,,,Tues. EPCOT,,,Mon. Animal Kingdom,,,Sat. MGM
Night time was three hours
Sun. MK,,,,,Fri. EPCO,,,,,Mon. MGM,,,,,,Wed. Animal Kingdom
Depending on when you stay your " Extra Magic " gets less and less. You have to leave your offsite room pretty early to get therre by 8:00 am. You may only have a 15-20 min drive to Disney Property but, you still have to get parked and get in the park and you never know what traffic outside or the timing on disney transportation will be.Plus staying 3-4 days you may not have the magic hours on the days you are there for where you want to go.
Don't get me wrong, if your not going to stay on site I agree with the other posters and would laugh for days

if you spent the extra money and it didn't pay off but ,you should at least be aware of the things that could go different from your plan.There is no rule that says you have to consider how your actions will affect others and we have all dealt with this in different situations.
