With the weather finally thawing, bashes are headed outdoors and, for event professionals on the coast, beaches are a fun option for casual receptions, alfresco dinners, and eye-catching stunts. From relaxed activities and festive decor to smart ways to integrate sponsors, here's a look at some inspirational ideas for seaside gatherings.

In 2009, Mattel celebrated Barbie's 50th anniversary with a bash for 200 in Los Angeles.

With the beach as a backdrop, guests picked up signature drinks such as Barbie Doll-icious, Ken's Caiprirosca, Strawberry Blonde, and It's a Pink Thing from an alfresco bar.
