HotelRatePRO at https://www.hotelratepro.com
provides services that I missed as a frequent traveler.
It went from an idea to a startup to a system in one year, and we have plans for many additional services.

Our services are focused on the needs of travelers staying at Top Hotel Brands of top hotel groups such as Hilton, IHG, Marriott, etc.

My problem as a Hilton Diamond member was that I wanted to book directly with Hilton to get Member-Only rates, collect points, and get other benefits. But I had no automated way to check if the price went down after I booked. This gave birth to the idea.

The services already offered are:
1. Hotel Rate Tracking for booked and un-booked hotels with an option for BrandSearch, which also tracks same-brand hotels near the booked/requested hotel.
2. Track Member-Only rates or Public rates.
3. Track Refundable or Non-Refundable rates.
4. Track Sold-Out Hotel for room availability, with BrandSearch option.

We send a RateAlert as soon as a lower rate is found. We send a RoomAlert as soon as a room is available.
For booked hotels you can set the minimum price-drop for an alert, so we do not send you an alert for a small drop in price.

We currently support the 48 brands of Hilton, IHG, Marriott and Starwood. Hyatt (with its 9 brands) will be added this month, followed by Wyndham (top brands) and Best Western. We plan to support almost 100 brands in about 12 hotel groups.

We plan to offer additional services geared towards elite members and the ability to do SearchMore - track near-by hotels of 3 brands.

Any feedback and suggestions will be appreciated. Thank you.

Answers to questions asked / comments made elsewhere:

1. "I worry about a service requiring personal info" - We understand this concern with new websites and this is the reason we do not collect ANY personal info from our customers. Sign up requires your email only, so we can associate confirmation emails you send us with your account and send you rate alert emails.

2. Many wondering "how do they make money?" - thanks for the concern. We have a road map with many additional Premium services that will require subscriptions and versions for specific biz market segments.

3. Special rates: Senior rate, AAA, Gov, etc. will be added in April-2017, together with specific room selection and additional hotel groups like Hyatt and Wyndham.

4. "I can do same on Yapta" - Yapta is geared to Corp market. We are very different than Yapta. With us you can track for lower prices booked hotels on Any website and UN-booked hotels. Focus on hotel brands with ability to track same-brand hotels near booked/requested hotel, to fit Loyalty members preferences. AND we are Unique with ability to track Member-only rates.
