Since there is no such actual place as the West Rim of the Grand Canyon then you are left with either the S.Rim or the N.Rim
Since the N.Rim's roads and facilities are closed for the season that leaves you with just the S.Rim to play with
FYI >Current S.Rim [86023 } temps are H-37F L-0F
Those are colder than the norms for this time of year But 7000' in a Ponderosa Pine forest will always be cold in winter
Personally I would skip the bus tour>I mean it's 4.5 hours from LAS to GCNP and instead book a tour on a carrier like Scenic Airlines-Airline Code YR-
You also may want to consider just renting a car and drivingg it
