As already mentioned, there are NO set routes. I primarily stay at BWV. The past two times we have taken DME there, we have stopped at POR/FQ first, then after us, the bus continued on to YC/BC.
Other times, the bus stopped at CBR before heading to YC/BC and finally BW.
There is no way to tell.
And you aren't going to be on a bus that goes to just one resort. The bus routes routinely have 3 resorts to stop at, sometimes 4.
The bus lines, at MCO, are split into specific resorts...so that could have been what you saw. They are not grouped by route.
