I made a small database of the 721 hotels in Singapore: www.teoalida.com/database/Hotels-Database-SAMPLE.xls
I am interested to extend the project for all countries but I need support from at least 3 people. I am expert in real estate and automobiles (see other databases made by me), so a hotel database is a NEW field for me. Please tell me what details do you require about each hotel?
On 27 September 2018 an Indian visited www.teoalida.com/database/cities and asked me if I have database of HOTELS… not sure what made him to ask about hotels in a page about city population. He needed only 5 columns: hotel name, address, city, country, star rating. His budget was very low so I could not do the job.
But making a world hotels database is a GREAT IDEA because it can be purchased by many people from all the world, not like car database, which require dozens separate databases for each region.
I attempted to use my universal scraper on Hotels.com and Booking.com and they have anti-scraping features. Tried also in TripAdvisor.com and here it worked at rate of 4 seconds per page, making the SAMPLE you see at top of this page (this website have also far less hotels than other 2, giving me a feeling to be far away from being complete). I can also ask my friends help to make custom scrapers for Hotels.com and Booking.com if you need a more comprehensive database (I need to pay them for this).
