What's the difference between marking A and B in a hotel?

The difference between the A standard and the B standard of the hotel mainly refers to the following two points:

1. The price is different. Hotel rooms marked A and B are mainly the difference in price. The standard A is an ordinary room, and the price is cheaper. Rooms marked B are generally superior rooms, which are more expensive.

2. Different hardware facilities. The hardware facilities of hotel standard A and standard B are also very different. The standard A room type generally does not include windows in hardware facilities, while the standard B room type includes windows in hardware facilities.
