My experience with Hilton has been that there are far fewer (upgraded) smoking rooms available. Also, at Embassy Suites properties, the 'good rooms' with balconies are usually non-smoking.

This has just been my experience (in the US)and I'm certain that it really depends on the property, the management company, the location of the property and typical guest profile.

As for international, I've never had a problem getting an upgraded, smoking room in Europe.
