I have booked a half day tour to the ruins with Native Choices. My plan was to get dropped off at Mahahual and go to the Krazy Lobster. How does this compare to just returning to the Costa Maya cruise port and hanging out there. Are there decent restaurants to eat lunch there? Enough things to see and do? We will be a group of 5 or 6 including 2 20 year olds and a 13 year old. Thank You.
