I am really leaning towards Ambar for a 12 day vaca in December. I love that we can choose quiet or be with more people at other parts of the resort. My only hesitation is having to make reservations. The last 4 resorts we have stayed at have been have what you want when you want. I live on a schedule and am afraid of feeling like I have one on vacation. My question is...how flexible are they if you are late or change your mind and want to to do something else? Yes, I realize there is a buffet but I don't want that for 12 days!
