Marco Polo (VCE) — not Treviso for a San Marco hotel
Most scheduled flights that mean Venice land at Venice Marco Polo (VCE). Alilaguna, buses and water taxis reach the lagoon; partner searches should mean VCE — confirm the code on the ticket.
Treviso (TSF) sits inland. It can make sense on some low-cost calendars if you accept the coach. It is a poor match for a late arrival into a San Marco walk-up with bags.
Non-stop from Europe versus a connection
From the UK and much of western Europe, Venice is a routine non-stop. A stopover via Rome or Milan is seldom useful unless it unlocks a better regional departure or a multi-city rail plan.
Airlines on this route
easyJet, Ryanair, British Airways and Wizz Air dominate many leisure schedules. Prefer VCE unless Treviso plus coach is deliberate.
Season and the last mile
Demand spikes around Carnival, Easter and summer. Shoulder months often soften outside school holidays. Water logistics with luggage matter more than the headline fare.
Then use the Venice stays guide. Confirm VCE before you lock a non-refundable room.
