Please reference Scripps IGS-IGPP meeting for a discounted rate.

As indicated in the first circular, 50 rooms had been
reserved for arrival on June 7, for 3 nights, departing on
June 11, for reservations made until May 7. We can no longer
guarantee that rooms will be available. This is the
beginning of summer season and the hotel is right on the beach.

Note: There is a problem that U.S. government travel rates
do not allow more than $89/night for lodging. Here are three alternatives:

Travelodge in La Jolla Birdrock area: $80/night (619) 454-0716
Travelodge La Jolla on Silverado:  $50-80/night  (619) 454-0791
Del Mar Hilton: $ 89/night  (619) 792-5200

Of the three, the Travelodge on Silverado is the closest.
This is not a large hotel, so rooms may fill up fast.
