I asked - along with several others- for this guide. She is obviously not still doing this, so don't bother holding your breath.
As to the Los Veranos tour - it was great and you made the mistake of not checking your receipt. That is ultimately your problem. So sorry.
MEXICO is rather dirty and lots of beggars - not just PV. Sorry you had a rough time. Don't bother going to Istanbul, China, So America - they all have beggars and vendors... but for true travelers, it is part of the experience. Don't want to knock you, but if you read guide boks they all say that is what to expect.
