Like most travelers, we'll be arriving on a Saturday and I was thinking of spending our first full day (Sunday) renting a golf cart and exploring the island to get our bearings. This would perhaps include breakfast at Mango, snorkeling at Garrofon de Castilla, lunch at El Pueblito, etc. Are most restaurants and other activities open on Sundays? Golf carts available? Is Sunday a good day to do this? What specific advice do you have for Sunday? (We'll be there the 1st week of September).
