Could we put up a tent on the same full hook-up site our parents' camper is on? We have another site reserved but our RV rental fell through, and it made us decide just to share the site with our folks after all. We want to know if we can have our own tent or if we will need to sleep inside their RV. Anyone know? If we can't put up the tent up on the same site, we'll keep the reservation for the 2nd site. TIA! Christy
