About 15,000 spectators are expected to use park-and-ride sites at Braywick Park and Stafferton Way as well as Upton Court Park, Slough, and Windsor Great Park, while recommended railway stations will be Maidenhead, Slough and Windsor & Eton Riverside.
Speaking to the Advertiser, Mrs May said: "Lots of people will be visiting the area and it's a question of how we can entice spectators to come and enjoy Maidenhead.
"The council and others are planning how we can ensure there's an offer there for those who've been here and watched the rowing to stay for longer and enjoy something in the town."
About 30,000 people will flock to the venue per day for the Games, which start on July 28, and the MP revealed she will be one of them.
"I applied in the normal way and the only tickets I got were for a couple of days of rowing," she said.
