Billionaire Mr Bezos, 61, and Ms S谩nchez, a former news presenter and entertainment reporter, are staying at the Aman hotel, a luxury 16th-century palazzo on the Grand Canal with a view of the Rialto Bridge.
They will exchange vows tomorrow at a black-tie ceremony on the island of San Giorgio Maggiore, according to Italian media reports.
The wedding itself is expected to take place in a vast open-air amphitheatre on the island, which sits across from St Mark鈥檚 Square.

Some locals say the A-list guests and their entourages bring good business.
Adriana, 83, said that 鈥渆veryone wins鈥 with the high-profile event, which has Venice鈥檚 famed luxury hotels booked out, and is likely to inspire others to marry there.
Samuel Silvestri, a 55-year-old shopkeeper and resident, said the city鈥檚 problem is day-trippers 鈥 鈥渘ot the sort of tourism that turns Venice into a little Monte Carlo鈥.
But critics have accused Mr Bezos of using the UNESCO site as his personal playground.
Environmental activists have also pointed to the carbon footprint of the mega yachts and dozens of private jets bringing the rich and famous to the city.
It is 鈥渁n excessive display of wealth and greed鈥, 51-year-old US tourist Christine Baker said.
