The SMI conference recommended hotels are Dan Accadia, Daniel, Sharon and Tadmor in Herzliya. Apart from Tadmor, they are located on the Herzliya beach front. It is a beautiful central location and by doing so it will make it easier for you to commute to the IDC venue as well. A shuttle bus will be provided from these hotels to IDC in the morning and back in the afternoon.
More information about the hotels can be found on their sites. They provide special rates for SMI attendees at IDC.
