Just back from a month in Puglia - Bari, Trani, Lecce, Ostuni, Gallipoli and Barletta. All in all a good trip, making up for plans that were kiboshed during Covid.
One thing we experienced in Puglia was the need for cash in hand - more so than in our other Italian travels. First, the Ostuni B&B host demanded cash at the last minute for our four-night stay. That surprise took virtually every Euro I had in my money belt. Then in Barletta we were enjoying our last Puglian meal when the power went out and the restaurant couldn't process payment by credit card. Bus tickets also were cash only from the driver.
Just glad I hit the ATMs when I did.
