ACL 2026 San Diego: Travel Guide and Where to Stay
ACL 2026 runs July 2 to 7 at the Manchester Grand Hyatt San Diego. The 64th Annual Meeting of the Association for Computational Linguistics is the flagship A* venue for natural language processing, and in the current era of language models it has become one of the most heavily attended conferences in all of computer science. This year that pressure is explicit: the conference is hybrid, and in-person capacity is capped at 3,500 attendees per day and expected to sell out. If you are planning to be there in person, register and book a room now, not after the camera-ready rush.
San Diego is having a busy NLP-and-theory week. CoNLL 2026, the Conference on Computational Natural Language Learning, co-locates in the same hotel on July 3 and 4, so many attendees will cover both with one trip. And just before ACL, COLT 2026, the Annual Conference on Learning Theory, runs June 29 to July 3 across town at the Bahia Resort on Mission Bay, close enough that some learning-theory people will roll straight from one into the other.
The venue. The Manchester Grand Hyatt is a twin-tower high-rise on the downtown waterfront at 1 Market Place, directly on San Diego Bay. ACL takes over its very large event footprint, and CoNLL runs in the same building, so the venue doubles as the most convenient place to stay. It sits beside Seaport Village, a short walk from the convention center and the Gaslamp Quarter, with the bay promenade out the front door for between-session walks.
Getting there. San Diego International (SAN) is one of the most centrally located major airports in the country, about 3 miles from downtown. The MTS Route 992 bus runs from the terminals to downtown in about 15 minutes, and taxis and rideshares are quick and cheap by big-city standards. Once downtown, the venue, the Gaslamp Quarter, and the waterfront are all walkable, and the MTS Trolley covers Old Town, the convention center, and runs all the way to the Mexican border at San Ysidro if you are curious.
When to visit. Early July in San Diego is about as pleasant as conference weather gets: reliably sunny, low humidity, and daytime highs around 24 to 27C with cool evenings off the water. The June Gloom marine layer has usually burned off by then. Pack sunscreen, something light for the days, a layer for the evenings, and expect the session rooms to be air-conditioned hard. Note that July 4 falls mid-conference, so expect fireworks over the bay and heavier crowds on the waterfront that evening.
Where to stay.
With capacity capped and two conferences sharing the venue, downtown rooms will go fast. All of the options below are within walking distance of the Manchester Grand Hyatt.
Manchester Grand Hyatt San Diego is the conference hotel itself, a waterfront high-rise with two rooftop pools, a full spa, and several restaurants. Staying on-site removes the commute entirely and keeps you in the middle of the hallway-track conversations that are half the value of ACL. It will book out first.
Marriott Marquis San Diego Marina is the closest large alternative, a bay-front resort next to the marina with two outdoor pools, a spa, and extensive grounds. A strong pick for attendees who want resort facilities a few minutes’ walk from the sessions.
Hilton San Diego Bayfront is a modern waterfront tower on the far side of the convention center, with saltwater pools and a spa. A little further along the bay but still an easy walk, and often better value than the two closest properties.
Omni San Diego Hotel at the Ballpark sits across from Petco Park with a rooftop pool, connected to the stadium by a sky bridge. A good mid-range choice on the Gaslamp side of downtown, and the Padres are usually home around early July if you want a baseball evening.
Hard Rock Hotel San Diego anchors the Gaslamp Quarter with a rooftop pool and an on-site nightclub. The pick for the younger end of the NLP crowd who want the city’s main nightlife district at the door, about a 10 minute walk from the venue.
Food and neighborhoods. The Gaslamp Quarter is the concentrated dining and nightlife district a short walk from the venue, dense with restaurants across every cuisine and price point. Little Italy, a 20 minute walk or short ride north, has grown into one of the best eating neighborhoods on the West Coast, with a Saturday farmers market worth planning around. San Diego is also arguably the best fish-taco and craft-beer city in the country: North Park and Little Italy are full of respected breweries, and cheap, excellent tacos are everywhere. Seaport Village, right next to the hotel, covers quick lunches between sessions.
If you have extra time. Balboa Park is one of the great urban parks in North America, with a cluster of world-class museums and the San Diego Zoo on its grounds, 10 minutes from downtown. La Jolla Cove, about 20 minutes north, has sea lions, sea caves, and some of the best coastline in Southern California. Coronado Island and its enormous beach are a short ferry ride across the bay. For a guided option, the Secret Food Tours San Diego walk covers the city’s food scene with tastings along the way, an easy way to spend a free afternoon eating well. Or for something faster and sillier, the GoCar talking car tour is a two-hour self-drive loop through downtown and Old Town in a tiny GPS-narrated buggy, a fun option for a pair of attendees with a free morning.
