We are planning to tent camp at San Luis in June. Our tent is 13x13. I know that the tent pads are 12x12 at sites that have tent pads. Does anyone have a recommendation for which site to reserve for a bigger tent? We also have 3 kids - 5, 6 and 8, so are thinking maybe we should choose one of the loops with a bathroom near it. I've looked on Google Earth but it's a bit hard to tell the scale.
