Excellent tour. I HIGHLY recommend Carlos!
Without question we were driven in the finest vehicle in San Juan. (seriously!) We have been on 13 cruises now and have always taken advantage of the ship's tour offerings as well as regularly hiring taxi's to provide these. If you have traveled this way you KNOW that these are generally done with large cumbersome buses (usually with inadequate air conditioning) and the obvious time constraints on your tour from having to load/unload large groups of people- and that the waits with older crowds for this can be quite long. Short of buses, small underpowered mini-vans are the norm on every island we've been to (25). After having been on a number of these I told my wife I was never again spending my vacation on a bus with poor views and a limited ability to get into the places their sheer size makes impossible. On Carlos tour we traveled in a full size AMERICAN custom Ford van, leather seats, a raised roof, GOOD A/C, drinks, snacks etc. Carlos gave a great tour and never let up on his running commentary except to answer questions. He even played a short video he had created regarding San Juan to show us additional things that time kept us from seeing.
If you've done your research in advance, Carlos will tailor his tour to meet your demands. Absolutely the best tour at the best price we've ever taken. I wouldn't even consider any other option after this and sadly know from experience, it's unlikely we'll ever top this tour for comfort, knowledge and the breadth of what we were shown in those hours.
My kudos to Carlos for his commendable efforts!
