My 3 DME experiences were perfect.
Sunday May 8, 2005, 9:30 a.m. flight landing, time from airplane exit to resort drop-off (CBR) was 63 minutes. This was my LONGEST DME time. Bus was maybe half-full.
Saturday November 4, 2006, 10 p.m. flight landing, time from airplane exit to POFQ was 56 minutes. Only 12 of us on the bus.
Saturday February 7, 2009, 8:30 a.m. flight arrival, time from airplane exit to Polynesian was 57 minutes. Just like the last time, only 12 of us on the bus.
By procedure, a DME bus is NOT supposed to wait until it fills. By procedure, from the time the first guest boards, the bus is supposed to leave within no longer than about 20-30 minutes. As you can see, I've never been on a full DME bus from the airport, and as you can also see, two of those times I was one of only 12 people on the bus.
When employees break the rules and procedures, the guests suffer. It sounds like that happened with numerous of the above posters.
