SF Bay Area to Henderson Executive (Las Vegas)

I'm planning a trip from Palo Alto to Las Vegas, landing at Henderson
Exec (closest airport to where we are staying). I'll be flying in a
Saratoga.

I'd like to benefit from other's experiences. In particular:

1) Best route from PAO to Henderson?

2) Best arrival procedure through Las Vegas airspace, such that we get
a view of the Strip (if possible) while not interfering with Class B
airspace? Is IFR recommended to navigate the space?

3) Best local flights, in case the "in-laws" want to go for a ride
(Lake Mead? Other?)? Any airports with good food on the property?

Any help and suggestions welcome.
