Airports
The best airport to land it for the wedding is the Ontario one, because it is only 20 minutes away from the city of Upland. HOWEVER, if you are flying in from far away and want to book a direct flight, it would be easier to do so from LAX.
Transportation
If you are planning on coming and don't have a ride with friends or family, you can either rent a car or uber to both the ceremony and the reception. Uber might cost a little more than usual due to the wedding being on a weekend. The only way to get to either or is by driving (Unless you wish to bike up Mt. Baldy in nice clothing).
Hotels
There are quite a few hotels in the area due to the closeness of the Ontario Airport. The closest hotel is the SureStay Plus by Best Western, which would cost $336 for a king size bed booked for three days two night. There are many others though! We suggest using the following website to see more options.
