hi guys,  
  
relatively new to the forums. would like to gather some inputs from all on the itinerary, as it's my first time to the States. 
apart from the sight-seeing, i'm proposing to head to these parks,  
  
new york: six flags (great escape) 
philly: hershey's park 
orlando: universal studios, disney hollywood 
boston: six flags (new england) 
  
only my gf and myself are coaster-goers, while the rest of the family are plain park visitors for theming and mechandize. 
not too sure if it's too themepark intensive, in addition to the sight-seeing. 
  
cheers!
