There is nothing wrong with collecting as much hotel data as you can - it's just how you use and analyse it that requires a robust strategy.
For example, hotel data can encompass social media, performance metrics, reviews, benchmarking, website usage and, of course, rates and pricing.
But many datasets are even more useful when combined with one another, this why a more strategic approach is needed.
Factor in resources - in terms of how often and who handles management of the hotel data - and it can get rather complicated for a property often already under pressure to get the basics of running a hotel right.
SnapShot has pulled together a very good chart, borrowing from the design of city subway maps, to illustrate how each pocket of hotel data works, how they interact and how frequently such information should be analysed.
