I'm glad you enjoyed your flight, I took my mother flying this past Sunday and my experience was a little different--I lost my radios after takeoff

. But I was able to maintain cool and everything was OK. My mother didn't even know what had happened until we landed and I told her why the flight was so short.
In regards to your flight to MCO, I am not sure. I have never flown around the area, although I will eventually(my brother works at Disney World and I'd love to take him up next time i'm in the area). I fly around central Texas and from what I've heard the only way they'd let me do a touch and go at DFW is if it was 3-4 in the morning and the controler was feeling nice. Some airports may also charge a landing fee, I think at DFW if I were to land it could be pretty pricey(I bring this up only because I am not sure how busy MCO is, but I think a comparison to DFW may be more accurate than a comparison to Austins airport which is only class C). My advice to you would be to ask a CFI familiar with the area.
In regards to the airspace that you brought up, you can never be too safe when it comes to not busting airspace. I was flying once with a friend of mine around the Dallas area and he accidentally flew into Dallas Love's airspace shortly after departure, but it wasn't a big issue, the controller politely told him to turn to a heading to get him away, but from what I understand it could have ended a lot worse.
On my first flight into class B sans instructor I was flying into the same airport that he encountered his little problem so I made sure brief myself on the airspace regions in the area to prevent that from happening to me.
