Back in 2008, my family and I were standing in line waiting to ride The Seas with Nemo and Friends. While in the cue line, there was a Brazilian tour group chanting (it was July) disrupting other guests experience. On the other side of one the walls in the cue area, a college age sounding guy screams "Go back to Europe!".

I was mortified and his buddies on the other side of the wall gave him no end of crap. At least his buddies were taking care of their loudmouth friend. (I wonder where this guy graduated as my kids 10 and 8 at the time made comments about Brazil not being in Europe)
In Brazil, they speak Portuguese - a dialect, true, but still Portuguese. If the group was on the other side of a wall, with no visual cues to tell him that the group was Brazilian, it is quite possible that the guy thought they were from Portugal, and Portugal
is in Europe. Not so stupid, IMO.
Unbelievably rude and inappropriate - yes. Stupid - not necessarily.
On the boat From WL to the MK a woman was talking to her (adult) daughter about there plans for their trip. She said "we'll take the bus from MK to Epcot".... I stepped in and said that there was no bus from any park to any park.... She corrected me saying "no no no,WE bought the special park hopper pass that allows us to go FROM one park TO another on Disney transportaion....."

there is no park to park service AT ALL.... hotel to park yes, transportaion center to park yes.....
To get from the MK to Epcot.
You can take the monorail to the TTC then transfer to the Epcot monorail
You can take a boat to the GF or Poly and take a bus to Epcot
You can walk to the Contempory and take a bus
etc..... etc....... etc.....
OK, your answer was incorrect. There is no park to park transport directly from the MK - they are all at the TTC. But when you say "there is no park to park service AT ALL" - that's just flat out wrong.
MK to Epcot > monorail/ferry to TTC, monorail to Epcot. (You are correct that there is no bus service to/from MK or the TTC to/from Epcot.)
MK to AK > monorail/ferry to TTC, bus to AK
MK to DHS > monorail/ferry to TTC, bust to DHS
Now here is where you were WRONG:
Epcot to MK > monorail to TTC, monorail/ferry to Epcot
Epcot to AK > direct bus
Epcot to DHS > direct bus/ferry (although you can also walk)
AK to MK > bus to TTC, monorail/ferry to MK
AK to Epcot > direct bus
AK to DHS > direct bus
DHS to MK > bus to TTC, monorail/ferry to MK
DHS to AK > direct bus
DHS to Epcot > direct bus/ferry (although you can also walk)
So you see, there is DIRECT PARK TO PARK SERVICE to/from every park except MK, at which you change transportation at the TTC.
So before you start laughing at people making "ridiculous" statements, be sure you have your own facts right.
