Show HN: I'm making a map of newly built hotels (opens in new tab)

1) I search on Google Maps for "hotels" and filter based on the hotel brand.

2) I search the reviews of the hotel for words like "new" or "old" to see what others are saying.

3) I also use Google Street View and look at previous dates of the location to make sure that even if the hotel says "new" that the hotel was not refurbished from a previous hotel.

4) I search on Google for any press releases or news reports of a new hotel built in the town.

Well, there is one reason -- if you prefer "old and dated" hotels to new ones. Lots of people do. That might be a useful option to your map: if you're tracking the age of hotels anyway, you could also produce a map catering to those who prefer the older ones.
