After years of work and millions in renovations, AC Hotel Pleasanton, formerly Sheraton Pleasanton, is now open for business.

On a recent weekday afternoon, a guest sat near a glass wall separating the lounge and pool deck, tapping at his laptop keyboard filling in a spreadsheet. Past the porte-cochere, new arrivals crossing into the lobby were greeted with a bright space and sharp modern design aesthetic softened by warm neutral colors, chill music and strategically placed accent lighting dialed-down to a pleasant glow.

“As with each AC property, every moment of the AC Hotel Pleasanton experience is designed to create a comfortable, elegant and unobtrusive experience that lets guests maximize their enjoyment and efficiency,” said Toni Stoeckl, global brand leader for Marriott Hotels.

The 171-room hotel at 5990 Stoneridge Mall Road opened earlier this month following more than $20 million in renovations, according to its operator, Hersha Hospitality Management. It serves food and beverage offerings from a full bar and kitchen, provides an open dining space, and a large pool deck, complete with an outdoor bar and cabanas for guests to relax.

It is a stone’s throw from Workday, Inc.’s shimmering new glass and steel corporate headquarters and a short walk to the West Dublin Bart Station. Like much of the Tri-Valley’s existing lodging stock, the hotel straddles the Interstate 580 corridor and is expected to draw its share of business and government customers as well as passers-through.

It also hopes to be an attraction in itself.

Unlike nearly every other wine region in California, the Tri-Valley lacks lodging with quality restaurant, resort and conference facilities.

This was among the key findings of the City of Livermore’s recently completed 2020-2025 Economic Development Strategic Plan.

Adam Van de Water, Livermore’s Director of Innovation and Economic Development, said that business and hospitality leaders surveyed for the plan identified a lack of high-end accommodations as an inhibitor to future growth and marketing of the wine region as a destination.

Both Dublin and Livermore are working to help spur the development of higher-quality hotels in their downtown areas.

Last week, the Dublin City Council rezoned a swath of land, at the Dublin Transit Center between Arnold Way and Campus Drive, to allow for the construction of a proposed five-story upscale hotel with nearly 200 rooms, under the Westin brand.

In Livermore, the city and a residents’ group both agree that the downtown area should feature a hotel, but are battling over the hotel’s location, amenities, size and quality.
