If you don't have a lot of money for decorations, consolidate to where the kids enter the building. You can create atmosphere in the other areas through music and activities, but you want their to be a wow factor when they enter the building so they get excited about what's happening for the week.
Rename your VBS to VBX "Vacation Bible Experience". It's easy to do and creates lots of buzz.
