Trip.com optimization for hotels is the work I do to make a property rank, convert and price correctly on Trip.com. I adapt your content for the Chinese and Asian traveler, set up promotions and flash sales, and manage the service signals Trip.com scores.
What I plan around in Haarlem: Keukenhof and the bulb fields; Amsterdam overflow at lower prices; Zandvoort beach and circuit events; Haarlem old town. Guests I price for: International visitors basing outside Amsterdam on 2 to 4 night stays. Where I start: Tulip-season premiums, pricing against Amsterdam and municipal holiday rental limits.
Haarlem sells mostly through Booking.com, Airbnb and Expedia. For Haarlem hotels I work on spring demand from bulb visitors, Amsterdam overflow, cruise and coach groups and weekend leisure, applying what I learned running revenue in five-star chain hotels to a smaller, more seasonal city where April and May decide much of the year.
The service in general is described on my trip.com optimization page; this page covers how I apply it in Haarlem.
