Brevity is indeed the soul of wit, especially when you are hosting your travel video.
Your online viewers have short attention spans so be concise.
Fight the compulsion to ramble on. Honestly, nobody finds you as interesting as you do. Remember that and you will do well. When filming your intro keep it at two short sentences or less.
Or if you want, cut away from the shot of you and use your speech as voice over, giving your audience something fresh to look at.
