Theme your site for the season. Whether you’re located in Hawaii or Colorado, choose pictures that help your prospects picture themselves enjoying your resort. Change pictures of people rafting or mountain biking to nice shots of people taking face shots in untracked powder. Better yet, configure your site to have a summer theme and a winter theme that your site visitors can select, and that you can quickly update to display as the default theme as needed.
Integrate real-time weather feeds and reports. Snow reports, surf reports, and tidal forecasts will bring potential travelers back to your site again and again, especially during the lead up to their vacations. If you have activity packages such as snorkeling, flyfishing, yacht rentals, lift tickets, ski lessons, etc., be sure to advertise them on your weather page.
