Bad idea, the reason why everyone use databases is because they are efficient.
If you have 50 rooms, 1 year of booking can be 18000 records, and you will have to read every single record for every single request, even worse every time you write a new record, you will have to lock the file, problem, it will prevent others from accessing that data. Believe me, it is not efficient.
So the advice is to learn databases as soon as possible.
