One of the most powerful things you can do to show someone you care is to write them a personal note. Not a form letter with their name dropped in, but an honest to goodness personalized message...relevant, friendly and timely communication.
Doing this takes extra time, attention and thought. But, in our fast paced, electronic world, that's exactly what makes it so special.
Doing this in a small inn is normal. Doing this in a large hotel is completely unexpected and a really nice way to say both "hello" and "thank you". I urge you to give it a try.
