My motel is a 50 mile one-way run - 25 will seem like nothing. I'm interested to read your review of the cabins after AirVenture - I've seen them listed as an option on booking.com for several years now and always wondered.
I'm 70 myself and well appreciate the incredible, long lasting value of air conditioning and indoor plumbing. I don't need fancy, but when I'm out of town I demand my own private bed, toilet, sink and shower - lol A TV, fridge and microwave are simply wonderful bonuses, but not mandatory.
I figure the year I spent in-country "roughing it" in 1972 more than satiated any desire for minimalist accommodations.
