docs(trip): update route and transport plan

 **Dates:** Wed Sep 30 → Sat Oct 3 (3 nights)
 **Guests:** 4 adults (2 couples) → 2 hotel rooms, or one 2-bedroom suite
-**No car** — this shortlist assumes the rental is dropped at LAX on Sep 30, followed by a flight to Las Vegas, so the group gets around on foot + rideshare. **Position on the Strip matters more here than anywhere else on this trip.**
-
-> ⚠️ **Route conflict to resolve:** the current [`itinerary.md`](itinerary.md) and [`bookings/car-rental.md`](bookings/car-rental.md) instead show keeping the rental through Oct 3, driving LA → Las Vegas, then returning to LAX. Do not treat either transport plan as final until the group confirms it.
+**Car available** — the group drives in from LA on Sep 30. KT & VT fly from LAS on Oct 3, while MS starts the drive back to San Francisco and returns the car at SFO on Oct 4. **Position on the Strip still matters, but hotel parking must now be included in every comparison.**
 
 > ⚠️ **Resort fees.** Nearly every Strip casino resort adds a mandatory daily resort fee (typically ~$45–55 per room per night) charged **at the property**, on top of the rates below. For 2 rooms × 3 nights that is roughly **$270–330 extra** — enough to reverse the ranking. Confirm the exact fee on each property page before comparing. Listings marked **NO RESORT FEE** below are the ones that avoid it.
 >
-> ⚠️ **Oct 3 departure airport is still TBC** (LAS or LAX — see [`itinerary.md`](itinerary.md)). If KT & VT fly out of LAX, an extra LAS→LAX hop is needed that morning; that argues for a hotel with an easy airport run.
+> ⚠️ **Parking.** Confirm the nightly parking charge and in/out privileges for every option. The rental remains with the group throughout the Vegas stay.

 ## Still to sort for this leg
 
-- **Day trips need wheels or a tour** — Hoover Dam, Red Rock, Valley of Fire and the Grand Canyon all require a booked tour or a separate Vegas rental (see [`vegas_sights.md`](vegas_sights.md)).
+- **Day trips** — the through-rental is available for Hoover Dam, Red Rock and Valley of Fire (see [`vegas_sights.md`](vegas_sights.md)).
 - **Shows** — Cirque residencies sell out; book before arrival.
-- **LAX→LAS flight on Sep 30** is still TBD in the itinerary.
+- **Oct 3–4 return drive** — choose MS's overnight stop / endpoint and coordinate the Oct 4 SFO car return with the SFO → YVR flight.
