Hi, our cruise will be in San Antonio port for a day, we've decided we want to go up to Valparaiso rather than Santiago to spend the day, and want to catch a cab there - can we just walk off the ship and get a cab without getting ripped off, or are there any handy hints on where or how to catch a cab without getting ripped off please? Thanks (PS also open to using one or someone for a whole day as a private driver if price is reasonable). Thanks so much in advance, regards Di from Australia
