We arrived in SJD airport. They dont really have baggage carts there, but there are men with carts who can service you for a tip.
First beware of the trip, when you passed customs and immigration you go into an area where people ask you if you are looking for transport. Tell them you already have it! These are your timeshare people, they make offers of free transfers, cab rides, free activites, free everything. Catch is you need to ruin one of the perfect days of your trip going to one of their 1.5 hour breakfast and tours (everyone we spoke to that went to one said they last more like 3-4 hours). We held out the entire trip, and by the end, they were offering, $500 cash and 2 bottles of tequila and a free nights accommodation. So keep walking if you do not want to get dragged in ... just their spiel inside the airport will take 30 minutes of your time.
Outside we found plenty of shuttles, one of which we took at a cost of $22. The first man you are likely to come into contact with, is not the driver, he is the organizer, he takes your money and you don't see anyone for a while, and you wait in the heat thinking you have just been swindled for the first time. We tipped this man, he looked perplexed and never thanked us ... we shortly later understood why. We waited an hour before our shuttled filled up and we finally left. We tipped again, so the trip cost more like $35 for 2 people. It turns out the taxis only charge $18 for the same trip and leave as soon as you are ready.
If you need to go to the bathroom in the airport, all I can ask you is, can you hold it? Perhaps the most foul bathrooms I have been in - ever!
You will notice the incredible vistas when you land ... it only gets better!
