I was there in low season but I did a great deal of research before going. From what I understand, it is best to get there early. I would want to eat breakfast before going, and the breakfast at the hotel is substantial. There are places in the park, but they are spread out and I am guessing that tour groups will fill these up. I would suggest that you take snacks and water with you. Also, the amount of time it will take you to get around the park varies with the path you decide to take. Hope this helps.
