If you have the € to spare, building Jacuzzi and demolishing them over and over I believe is one of the most exp you can get per time. There's not much point after lvl 33 since it adds no new buildings to the game. (Yes, it pretends to add the Aerostat at 34, but not really.) Without buying € or cheating, it takes at least a year to get all the Awards.
