The Challenge
The challenge was to develop an online hotel room booking engine website where hoteliers can register & maintain their database for availability of rooms. One should be able to register & login, search the hotel rooms & check for availability, book a room & if needed cancel the booking. Registered users should also be able to pay online using PayPal & Credit Cards for their bookings.
The Solution
The website allows users/hoteliers to register & maintain their account online. Hoteliers can list their website & maintain the statistics of availability of rooms. User can also search, book, pay & cancel hotel rooms. Access to the detailed specific country & city guides is also there for user's convenience.
The Technology PHP & MYSQL
The Benefits
This is an online hotel room booking engine website with features like search, book, cancel & pay online. It is very easy to book rooms & pay online through this website. This website provides wide range of hotels with various categories in rooms.
