One-third of Hilton-brand hotels in California are in the process of completing renovations to their properties, Hilton Hotels & Resorts announced last week. The renovations, which combined are costing more than $100 million, are part of a global initiative by Hilton to upgrade its facilities in pursuit of improved guest satisfaction."With our headquarters in Beverly Hills, our California hotels are a particular source of pride for us," Hilton's Senior Vice President of Brand Management Jeff Diskin said in a statement. "The Hilton hotel brand has a proud tradition of providing its guests with the latest in stylish, valuable amenities and services. This ongoing renovation program will bring the brand to the highest service levels among upscale hotels. Guests are already noticing and commenting positively on these recent changes, which has driven increases in guest satisfaction scores."At least 15 of Hilton's California properties have completed or are currently completing improvement projects this year, according to the hotelier. Among them are the Hilton San Jose, which is adding approximately 2,500 square feet of meeting space adjacent to the San Jose McEnery Convention Center; the Hilton Sacramento/Arden West, which has spent $4.2 million to renovate its meeting space; the Hilton Irvine Orange County Airport, which has refurbished its meeting rooms; and the Hilton San Diego Airport/Harbor Island, which made over its banquet facilities in May 2008.
