We, too, had a very long trek from our room to the Mara. If you plan on using a car to get to the parks, you might think about bringing your mugs with you each time you leave the resort. That way upon your return, you can stop at the Mara for a drink before returning to your room.
The AKL mugs were nice in that you had two style/size options to choose from. The mug was also larger than our other resort mugs.
