ALT+[Z] = Get All Rides
CTRL+[Z] = Get All Shops
SHIFT+[Z] = Get All Facilities

Build on Shops:
First, get or build a shop. Then if you need a toilet or another attraction right with the shop but no room, right click on a spot (not the entrance) and it will delete that part of the building, but it looks the same. Then put the toilet or attraction, even a shop there. It might look like its not there, but it is.

Mega Park:
For a megapark, enter your nickname as DEMO, then continue. This will load up a Megapark with most of the rides but a few problems for you to fix
