Member Portal and Booking App Development

I need a developer to build a member portal and app for booking hotel stays with our 4 partner hotels. The project should include night balance tracking, a weather widget, and a smooth booking experience for members. Bookings will come to us and we will then interface with the hotels. No interface with the hotels will be necessary. The solution should be built using Softr and Airtable or a similar platform. Please share relevant experience with similar booking systems and your approach to creating a user-friendly interface for members.
