ADO Bus Lines of Mexico now has a regular bus that leaves Belize City at 8:00 P.M. from Novelos Terminal and arrives at PLaya Del Carmen around 5:30 a.m. and then onto Cancuns airport arriving around 6:30 a.m. I just took this route on Sept 10th and it worked out well. Although I have yet to take the return trip, I believe the return trip leaves Cancun (airport??)around 10:00 p.m. and arrives in Belize city around 6:00 A.M. . This New service now potentially avoids an over night room in Playa. ....Yippee...
