According a recent study performed by iPass, a mobile roaming software company who provides roaming services to Fortune 1000 companies, and is an Innflux partner, poor-performing Wi-Fi systems will drive away hotel guests. 

As AUSBT reports here:

"We know that Wi-Fi access at hotels is an expected necessity for many business travellers these days but a new study from iPass goes even further,
suggesting that hotels that have poor Wi-Fi service and availability may be losing more than a third of their business travel clientele.

The study comes from iPass, a provider of ‘enterprise mobility services’ (read: global 3G and Wi-Fi connectivity for corporate clients),
and highlights the increasing demand for high-quality Wi-Fi connectivity from business travellers.
Perhaps the most eye-opening statistic is that these days, 36 percent  of business travellers will take into account a bad Wi-Fi experience
 they’ve had at a hotel when deciding whether to rebook - and that for  16% of business travellers this bad experience can influence their  
decisions about an entire hotel chain. 

Interestingly, it’s the older business travellers that are the most  unhappy when there are problems with Wi-Fi connectivity at hotels, while  
business travellers aged 22-34 are more forgiving - just 25% of this  age bracket said that they would not re-book with a hotel where they  
have had a bad Wi-Fi experience. 

The findings echo the results of a Deloitte study undertaken last month, which found that 79% of those interviewed agreed  with the statement 
"Complimentary high speed internet in my room is  important to me".

For those of us that are frequent travelers and users of WiFi already, this isn't news as much as it is validation that indeed WiFi and HSIA in general is extremely important to hotels guests.
