Flight
The Menlo Park area is halfway between San Francisco and San Jose airports, but SFO will likely have more available flights. Both are about 30 minutes to/from without traffic.
Hotel
We have a negotiated rate of $149/night for the weekend. To use the group rate, click the link below or call and mention you are part of the Donner Wedding by September 29. (You may still be able to get the rate after that date, but the hotel cannot guarantee availability.)

House Or Rental
While there are a number of hotels in the area, Airbnb or VRBO is always a great option for groups.
Travel Note
Ubers and Lyfts should be readily available in the area and are recommended transportation throughout the weekend.
