One-way SFO->LAS drop was too expensive, so the rental runs Sep 19-Oct 3 and everyone departs from LAX. Also record KT & VT arriving SFO at 1 PM on Sep 19.
Booking modified Jun 24: checkout Sep 26 -> Sep 27 (3 nights), total US$542.73 -> US$771.16. Sep 26 becomes an extra Sequoia/Kings Canyon day, still unplanned.
