The no bathrooms part is the deal-breaker for me. I'll be staying away.
Here's the link to what will happen to the parks in event of a shutdown:
https://www.doi.gov/shutdown The link is from January 2018 but still applies.
"Park roads, lookouts, trails, and open-air memorials will generally remain accessible to
visitors, but there will be no NPS-provided visitor services, including restrooms, trash
collection, facilities and roads maintenance (including plowing), and public information.
- As a general rule, if a facility or area is locked or secured during non-business hours
(buildings, gated parking lots, etc.) it should be locked or secured for the duration of the
shutdown.
- The NPS will not operate parks during the shutdown – no visitor services will be
provided. The NPS will not issue permits, conduct interpretive or educational programs,
collect trash, operate or provide restrooms, maintain roads or walkways (including
plowing and ice melting), or provide visitor information."
