I am going to Coastermania for the first time this year.  I have friends who are coming up from Florida and this will be the first time to CP.  Last weekend when I made my first visit since Fast Lane was introduced, I was shocked by how much slower the "stand-by" lines were than they used to be.  My friend and I were unable to ride all the big coasters (Mav, GK, TTD, MF, Raptor, Mantis, Magnum, WT, Gemini) in one day. 
  
If we utilize the ERT at Coastermania, will we have a problem getting at least one ride on everything?  I know Coastermania is one of the largest enthusiast events, so I don't know how long the lines are during ERT.   
  
Can someone share their knowledge please? 
  
Thank you very much!
