Feedback that we also got from clients confirms what we thought – free WIFI (within reasonable limits) sells rooms.
Properties are offering anything from 50mb to unlimited data via WiFi. Most are around 250-500mb per day. Even 50mb is adequate for emails and general browsing as long as lots of images are not being uploaded to sites like Facebook.
Our advice is to offer free WiFi. And remember to make it clear on your website that it is actually free and what the limits are. If this is not stated, people will probably go elsewhere rather than enquire about it from you. Too many sites we look at do not have this information.
There seems to be a relationship that the more expensive the room, the less chance that free Internet is offered. High daily rates charged by some higher end properties are certainly turning off customers.
