I did not understand your question.
As default, in accommodation page and contact us, it shows google map.
Please check http://www.soaptheme.net/wordpress/travelo/accommodation/hilton-hotel-and-resorts/ and http://www.soaptheme.net/wordpress/travelo/standard-pages/contact-us/
How to enable google map on the contact page, and also on every hotel page(map tab)?
