For those travelers who might be (now) planning a wintertime trip to Acapulco in MARCH (2008) ... please be WELL-ADVISED ... well enough in advance ... that Spring Break and Semana Santa (a/k/a "Holy Week" - one of the city's BUSIEST tourist week's of the year!) will overlap.
Semana Santa actually begins in mid-March (very early next year) ... as Easter Sunday (Domingo de Gloria) is a movable Christian feast-day.
March 16th marks the actual beginning of Holy Week 2008 ... and falls smack-dab in the middle of the Spring Break season ... which mean that Acapulco's main-bay area will be absolutely JAM-PACKED (worse than sardines!) - and hotel-rooms will almost-certainly be both premium-priced - and scarce!
In addition, it's typical (during Semana Santa) that taxis and restaurants respectively jack up their fares and menu-prices ... so you might also want to keep that in mind.
A word to the wise ... ;-]
Plan according to your needs - but don't say you weren't forewarned.
