The third hotel that we have is the Hilton Garden Hotel.
Below is a link for reserving a room:
The Hilton is within walking distance of the festival and right across from the ferry terminal. It is the most convenient of the three hotels. NOTE: The "water view" rooms are more but the city view is OK too. You will have a water view all day at the festival. The rate they have offered is a significant savings from the regular rate.
If people are on more of a budget and have questions about anywhere else to stay just let me know.
