We used the grill on our last stay at BCV. Use one of those charcoal bags that you just light the whole thing (matchlight). Also, don't get the smallest size bag as the grill is good sized and my fire was not quite hot enough to cook everything through. I had to finish the burgers off in the microwave...they still tasted good!!
Be sure you pack everything you will need for cooking. It can be a long walk back to your room for a spatula. Also, the ashes (from the previous user) may need to be emptied, a big metal spoon, paper towels and plastic waste bag were helpful for this. The grills get rained on, so the ashes, etc. may be sloppy and water-logged.
We usually cook two meals on one night and have the leftovers the second night. That way we use the grill only one night and buy only one bag of charcoal.
Items to take to the grill:
a metal spatula, and big metal spoon (we bring one from home)
Paper towels/plastic bag
Charcoal/matches
Food to be grilled
Clean plate
Foil
Favorite beverage
Have fun!
