Nor mine! And I'm sure everyone will have the same idea, which is my worry-- that they'll get so overloaded (or anticipate getting so overloaded) they'll start throwing people out. Won't know until I try, though... (Hoping I won't have to, but being able to book a room for a reasonable price is just too good to be true...)
Have you checked out towns west of the eclipse path for reasonably priced accommodations? Probably less traffic issues on the west side of the path vs the east side of the path (and all the big cities).
Texas Towns West of Eclipse Line roughly North to South include Pottsboro, Denison, Sherman, Gainesville, Valley View, Sanger, Chico, Bridgeport, Denton (Just N of Dallas), Decatur, Springtown, Axle, Mineral Wells, Mills, Santo, Gordon, Thurber (On I20), Strawn, Eastland, Gorman, DeLeon, Early, Santa Anna, Brookesmith, Lohn, Ballinger, Paint Rock, Eden, Melvin, Adams, Juno, Carner, Windmill, Comstock, Langtry. I really like Menard, Eldorado, Sonora, Eden, San Angelo and surrounding towns because they are generally west of Lake Buchanan and other large bodies of water. Viewing the eclipse over large water bodies can reduce afternoon clouds (at least that is how it worked for me in 2017).
