yes, a person could stay one night at the one site hotels, next night off site then back on the third day/night at on site and receive the 4 days of fotl perks.
but geez.........all that moving ........its gotta get to ya...
i go to the parks when they open and stay until they close down. i would hate to move from on site to off site just for the perk........
i mean, you stay on site, use the key for the fotl and at the end of the day relocate to an off site hotel.
then, go to the on site hotel on the morning you check out of the off site hotel and check in again on site...............repeat process again.
whew........makes me tired just thinking about it.
more power to you if you can pull it off.
