It seems that since August 2012 it is not possible to buy Machu Pichhu entrance tickets via the http://www.machupicchu.gob.pe/ anymore. Can someone give me the name of a travel agent or an online vendor that they may have used to pre-purchase tickets for Machu Picchu. Someone with you had a satisfactory experience (that is, you got your tickets for the date you reserved them), so that I can trust giving my credit card number. I only need the tickets and not a package. Thanks a lot.
