Free Wi-Fi makes people spend more
Free-Hotspot.com has published a survey carried out over 6 European countries and interviewing 1000 Wi-Fi users. The conclusions were that 64% were more willing to buy something from a business offering free Wi-Fi and 96% would return again.
This is perhaps not rocket science, since most people would rather use a free service than pay £5 for a one hour Wi-Fi access token. Among business travellers one suspects that many do look to find a hotel that offers free Wi-Fi access in the cost of the room.
