The answer to your question is "Soaring Buzzard Conference Room." The problem is that in English, at least in the United States, the word "buzzards" are a kind of bird often seen circling over carrion (dead animals). In US culture, buzzards are unpleasant birds. They would not be likely to be chosen as a mascot. Find out the real scientific name of the bird you are calling a "buzzard," and then try to find an English name for a similar bird, that we think of as noble, courageous, glorious, and brave. Or do a Google Images search on "soaring birds" and pick one that looks right. If you can't get anything more accurate, try "Eagle." "Soaring Eagle Conference Room." Seagulls also soar and ae considered beautiful; the "Soaring Seagull Conference Room" would also work.

The first option is best: all capitalised and no hyphenation.

One more question: Should I use 'The' in front of 'First (Second, etc.) Conference Room'?

Thank you, Greg! I appreciate it.

"Lake View Hall" is a very good choice. The other choice doesn't work.
