Update - 8 Jan 2019: Please let me know where you will be staying once you have made your reservations, that way we can try and head to the event as a group.
I will be staying at:
SLEEP INN & SUITES
2810 State Highway 361
Ingleside, TX, 78362, US
The rates there seem to be very reasonable.
Here is the route:
There are several food options near our stop in Kenedy,TX. Planning on spending at least 45minutes there for fuel/food & Rest. One more stop will be made in Refugio, TX, prior to arriving in the Port Aransas area. 2 of us so far are staying at the Sleep Inn in Ingleside.
FYI, you will need to reserve your accommodations on your own. I have been told that hotels fill up very fast and can be pricey, so if you plan on going, please make reservations ASAP. Camping may also be available near the event(on Mustang Island).
