If you want convenience at a cost, then mas OK kung magrent mo van. Sa akong experience ok rman mag Victory Liner from pasay to baguio. Remember it is an 8-hour journey on regular traffic, sa bus maka change position ka whereas sa van imagine mura kag sardinas lisod lihok. They also have the premium coach nga naay toilet on board and large seats, if could remember in 2011 the fare was around 700 pesos.
Goodluck on your vacation..
