Which Punta Cana resorts allow true unlimited a la carte dining at dinner time? Which have sit down restaurants for breakfast and lunch? We might do buffet by choice for the early meals some days, and can probably deal with it every day, but have a strong preference for sit-down dinners. Trying to decide if an AI is the right choice for us or not. We will be travelling with a young child as well, so adult-only facilities won't work. Thanks!
