Okay, just a chance to rant, these are my opinions on all the Disney parks.
DL- Needed (duh!)
WDW- Needed a park on East coast since only about 4% of DL's vistors where from the east coast
DLP- Its sort of unneeded but I suppose the Europe Market needed one but more people from the UK go to WDW for the whole 'florida' idea then DLP
TDL- As nice as it is, unneeded
HKDL- Completely unneeded.
Bangkok/Shanghai DL (plans)- Completely Unneeded
I guess I just don't want Disney Mexico or Disneys Texas Adventure.
