You’ve found your way to Southwest Florida, left the mainland behind via the causeway bridge and survived the trek down Captiva Drive to reach your vacation Valhalla – the ‘Tween Waters Inn.

Still, if you’re thinking the most challenging part of the voyage is done… think again.

Now that the suitcase is unpacked and the shoes have been exchanged for sandals, you’re going to have to fill the hours until it’s time to repack, refuel and re-board for the return trip to reality.

It’s surely a daunting task for someone unfamiliar with our sunset-centric way of life.

But fear not, excited traveler. Your TWI INNsider team has got you covered.

In fact, we’ve made it as easy as your ABCs.
