There are two hotels in Tiburon that are walking distance to both the church and the yacht club:The Lodge at Tiburon: A large hotel with rooms starting at $169 per night.
The Waters Edge Hotel: A smaller, higher-end hotel with rooms starting at $189 per night.
We recommend booking your room for Sunday May 28 as soon as possible since that is Memorial Day weekend.
We recommend staying at one of the above Tiburon hotels so you don't have to drive on Sunday, but there is another hotel that is a 10-minute drive away, Acqua Hotel. Acqua's rates seem to vary, but you might find a lower rate on Expedia.
