TTC - getting back there?

[Ellelledee]

Yesterday we had a really good day thanks to my excellent fast pass planning skills this year 😂😂😂 then it came to leaving and everything went belly up!
Our hotel shuttle drops us at TTC - fine and dandy - the driver tells us how to get to other parks (we knew anyway but again fine and dandy and very helpful to others who haven’t been before) note the stop to return.
So leave animal kingdom to go back to TTC - don’t see a TTC stop so assume it must be MAGIC KINGDOM - no that goes to Magic kingdom 🤔. So how do we get to TTC? We decide we have missed the hotel shuttle now anyway so we aim to get to a park as near to our hotel as possible and get a taxi - EPCOT. So we get to MK and think monorail - with all the construction I can only see the Resort monorail - THEN google and realise the other one is the express monorail so this is the wrong one but it goes to the TTC and we are in a big queue and commutes so can’t swap 😂😂. So we go to TTC and then monorail to EPCOT 😩.
Is there any other way of getting to TTC from the other parks?
Why do buses run from TTC to parks but not back?
