We went to San Miguel & stayed at the Furnas Boutique Hotel in late March, earlier this year. It's a great hotel & restaurant. They have a gorgeous indoor pool heated by the hot springs there. The island is very lush & green & is said to have more cows than people. We did some hikes and drives. Whale/dolphin watching excursions are big & San Miguel gets a lot of cetacean traffic. Very fresh seafood. Found Ponta delgada a bit run down and sad, but we were there off season. We flew in from Lisbon for 4 days with a 1h time difference and it was about the right amount of time.
