Is smoking on hotel balconies allowed in Nha Trang?

Some hotel reviews mention balcony cameras that catch smokers, with fines charged at checkout — but this isn't confirmed.

Balcony cameras weren't spotted even in 5-star hotels, but some rooms have a fire alarm sensor on the balcony.

Many hotels post no-smoking warnings for balconies with possible fines, but in practice the rule is often not enforced — smoking is very common in Nha Trang, including inside hotels.

Generally hotels with balconies allow smoking there, with only a few exceptions — no need to worry in advance.
