Wish I could give you something concrete, but it would seem that DME is very 'fluid'!!! I have had several experiences, dh has had one and a friend has had one.....I was staying at POP twice. First time I was the first stop, then the bus went on to AKL and another resort (CSR I believe). Then, last May, again I was at POP. However this time, I was last on the bus...AKL first then CSR, then me. When dh used DME the following day his bus stopped at POP first, then AKL. My friend, if I remember correctly, had the reverse experience...she went to AKL first, then the others.
I guess it depends on the driver.
