On this point, there can not be a single opinion, it all depends on your personal preferences. All inclusive - if you prefer to spend most of the time in a hotel and the prospect of going out to dinner in a restaurant outside the hotel does not appeal to you. Half board is good for those who like to eat outside the hotel or who prefer a light fruit snack in the middle of a hot day. Only at breakfasts there is a relatively small number of hotels. To my taste I would recommend half board - near any hotel you will always find a lot of restaurants, and among other things, it's a great occasion to get acquainted with local cuisine.
