Going to the seaside was a popular Victorian recreational summer activity. Different resorts catered to different social classes, and Broadstairs in Kent attracted more upper-middle class people.
Visitors would stay in comfortable hotels and eat and drink copiously. They could walk along the promenade or esplanade, and listen to a band play or watch a variety show.
Seaside towns built piers for mooring boats, and these became promenade venues. Some had dancing or amusement booths at which tourists were charmed into parting with their money.
