The routes
Budapest to Siófok is 105 km (~1h15 by car); Balatonfüred 130 km (~1h30); Keszthely and Hévíz around 190 km (~2h). Summer weekend traffic on the M7 motorway can add 30–60 minutes.
Taxi vs private transfer vs train
Regular Budapest taxis (Főtaxi, City Taxi, Bolt, Uber) rarely accept long intercity runs to Balaton, and if they do, the metered fare gets expensive fast. Most travellers pre-book a private transfer for a fixed door-to-door price. The train from Déli or Keleti station is the cheapest option but runs on its own schedule and drops you at the main station, not your hotel.
What to expect from a private transfer
Fixed quote covering driver, fuel, tolls, parking, and insurance. Pickup from any Budapest address or directly from Budapest Airport (BUD). English-speaking driver, child seats on request, and space for luggage — the usual choice for families and groups.
