The nearest airport is Palm Springs International (PSP), about 20 minutes from the hotel (there's even a direct flight from Toronto!). Car rentals and rideshare are available at the airport. Other airports are roughly 1–2.5 hours away:
ONT · LGB · SNA · SAN · LAX · BUR
If you're staying at the Sands or nearby, rideshare is a great option once you arrive.
