Be firm and stand your ground and DO NOT stop if you don't want to look. Don't go over if someone calls you over. Just say no, and be firm. Don't waver - they can sense it if you are wavering. Be sure to get the cab fare worked out before you get in - if it's a route taxi, say, "$1.50 to the roundabout, right?" or something like that so they don't try to charge you more. Don't be shocked at the amount of $ you drop on tips - that was the only thing that really surprised me. We knew it was low season and made sure to tip 20% on meals (like at home) and a few bucks here and there for anything special or out of the way someone does for you - gets you a cooler, refills your ice, carries your bags, etc. Don't be afraid to, with caution, walk and see new stuff, try yard food, etc. Ask the locals if you're wondering if something is good - we found Erica's that way, otherwise we'd never have sought it out on its own. Don't be afraid to haggle - we got some good deals and some okay deals on things that we really wanted (we had very limited time and basically no time to shop, so we had to take what we could get for gifts for those we left at home). If you get coffee to bring home, go to the grocery store - much cheaper there - we went to HiLo. And finally, if someone was having a hard time taking our "no, thank you" for an answer, we said it again and then added, "respect!" and that ended it.
