SpringHill Suites by Marriott San Diego Carlsbad is a 104-suite property on Carlsbad Boulevard that debuted in December 2020 directly across from Carlsbad State Beach. Managed by DKN Hotels — a Southern California hospitality group founded in 1984 — the all-suite format puts it on the same coastal corridor as Carlsbad Village breakfast institutions such as Swami's Cafe Carlsbad on Carlsbad Village Drive. Every suite separates sleeping, working, and living zones and includes a West Elm convertible sofa that transitions from couch to daybed to trundle, accommodating up to five guests per room. Tower39 Rooftop Lounge, added in January 2024, serves craft cocktails and shareable small plates around fire pits with panoramic sunset views, and the venue is available for full-buyout private events — a format that complements dedicated wedding and reception spaces at nearby Carlsbad Windmill by Wedgewood Weddings. Suites measure approximately 450 square feet and include microwaves, mini-refrigerators, and in-room streaming access via integrated smart-TV platforms.
