Điền từ thích hợp vào chỗ trống: We are goingto stay ...... a hotel

When we're talking about what hotel you stayed or are staying at, I understand the preposition of choice is "at" rather than "in." 

1. Use "stay in" with large areas such as big cities, towns, countries or continents or streets, areas, zones; means of transport: plane, car, bus, train, ship...

2. Use "stay at" with relatively smaller places: flats, houses, hotels, restaurants, clubs, banks, theaters, cinemas, airports..; some points (điểm): at the corner, at the bus stop, at the door, at the entrance, at the end of the road, at the crossroads, at the front desk...

"in" nha bạn

We are goingto stay in a hotel.

Vd nhé:

Right now, I am in the hotel to have my breakfast.
Right now, I am at the hotel to have my breakfast.

The first sentence sounds me as if I am inside the hotel right now to have my breakfast.
The second sentence sounds me as if I am at the entrance of the hotel to eat something available on the carts.

...stay at...
