Time Share vendors
Local sales people will approach you and offer a free breakfast, free meal or some such deal in order to have you attend a time-share sales presentation. Time-shares are sold to tourists and offer a week at an existing condominium. Prices vary widely.
Unique Suggestions: If you are not interested in purchasing a time-share condominium, simply smile and say "no, gracias" and walk away. They generally won't bother you any more, they will look for the next tourist. They often are located in booths labeled "tourist information". Most speak English quite well. They receive a commission for each person they deliver to a sales presentation.
If you are interested in what they have to say, agree to attend a presentation. They will take your name and the name of the hotel in which you are staying. They will come and pick you up - if you don't show up, they don't get paid. You can usually negotiate more than a free breakfast - they will give you a gift-certificate at one of many fine restaurants (some good for $50 US). Be prepared to listen to a high-pressure US or Canadian salesperson for three to four hours. They insist on purchasing at the time of the presentation, and generally don't allow you to take the paperwork home to be examined by an attorney. They'll say the sale is for today only.
Fun Alternatives: If you want to avoid the time-share people, be polite but walk away. Remember, this is how they make their living. If you are truly interested in purchasing a time-share, remember that the 50% of the cost of one purchased that way goes to cover marketing. The salespeople have a pretty fair rate of concluding sales. Also, if you check out the internet, you will find people who are selling their time-share for 1/2 to 1/4 the price.
Beach vendors can be annoying - Ixtapa and the nearby town of Zihuatanejo have beach vendors. Their numbers are not like that in Cancun, Puerto Vallarta, Mazatlan or Acapulco.
Unique Suggestions: Generally, these hard-working people try and make a living to support their family by selling goods along the beach. If you don't wish to be bothered, avoid making eye-contact. If you are approached by a vendor, if you are not interested in what they are saying, simply smile and say "no, gracias" and they will leave. Vendors are generally polite and gracious.
Fun Alternatives: Actually, don't be too quick to rule out some purchases. Generally, the vendors charge a bit more than from the various shops that are nearby, but the vendors are convenient. They sell hats, beach towels, t-shirts, blankets, rugs, etc. It is okay to buy food products from the vendors (like peanuts). For silver, you can negotiate fair prices for silver items, silver is plentiful there and is mined nearby. However, your best bet for silver is in local shops where they sell silver jewelery by the ounce.
