When you "cut and paste" the address for the web site for the Guide Book:
Paste into a definite address line in your explorer (or similar) and it will have an immediate response.
If you place it into a search engine it will not give you a correct site, just sites with "something like it"
I tried it, it does work.

Thank you for giving us the e-mail address to this wonderful site. I really enjoyed looking at it and will use it to help plan our next week at Casa Ybel.

That was a "Thumbs Up" that I clicked on
