Whatever I feel like on a given day. I hate itineraries. I like going on vacation with a general idea of what I can do, and then picking and choosing when I get there.
That’s difficult to say, because it’s entirely dependent on the destination.
I like both urban and scenic exploration. I have trouble sitting around, unless my body needs the rest. So, I stray away from most “leisure” activities. Sitting on the beach for hours is not for me. If the destination has a high walkability factor, I will walk everywhere I physically can, and I will do it A LOT.
I barely take any pictures. I find that they detract from my being in the moment, and they never capture what I hope.
I do like thrifting for niche, often older electronics and peripherals.
I like food.
I like cigars, and love cigar bars, because the atmosphere and activity is excellent for meeting locals and travellers alike. That is one thing I will always scout out and do.
