Please critique my Pugia itinerary

I am surprised you had an easier time finding accommodations in tiny Locorotondo over those larger places, but it's pretty and you will love it I'm sure. I would just make sure you are prepared for translating parking signs if your place lacks dedicated parking. Funny aside, whenever anyone says you can never get a bad meal in Italy, I always think of Locorotondo, where I was given a sandwich that was inedible--to the trash it went. (Not that that says anything negative about the town, it was just one of those things!)
I never think three nights is too long anywhere, but you have plenty to full your days so I def don't think so here.
You might want to switch days 3 and 4.
Looks nice to me!

I'd want more time in Lecce, but I don't know where to suggest you find that extra time.

Since you are in Locorotondo you should visit Alberobello, only 5 min drive.

Thanks for the suggestions. We can also come back by Lecce on our last day. And yes we will visit Alberello while in Locorotondo. I’ve read early or late would be better than the middle of the day. Maybe, we could have dinner there. Any restaurant suggestions?

I love Bari. If you can, I would spend time there touring the Old Town which is like no other.
You might check to see if there are any performances at the Opera House while you are there as well.
Honestly, 8 days in Puglia is not nearly enough!

I agree with Carol. There's a lot of transfer time on this trip. Might you consider just concentrating on a smaller area and saving other places for a future trip? There's a lot to see in Puglia:
