Costco Travel

**Low level items:**
 * The color scheme mostly consists of blue, red, black, and white (background) which are the colors of their logo. I like the consistency of the use of color it makes the webpage appear nice and organized.
 * The font size is appropriate and can be maximized without assistive technology
 * In order to consider everyone, I recommend that an alternative page with black and white images and text should be available to users with color blindness
 * For example one of the maps has blue font text on top of green background([|map])
 * A color blinded person with absence of blue sensitivity would see the image as blue text on blue background. (not readable)
 * The layout is consistent throughout the site.
 * On each page the search form is place on le top left, package deals appear in the center and the useful advertisements, related to the package selected, appear on the right and lower left side.

**Middle –level aspects:**
 * The placement of the search form, search bars, advertisements, logo is consistent
 * The font color and size is consistent
 * The color scheme is consistent throughout the site
 * The user form is designed so that the user cannot make serious error. The user is given the option to enter the city they wish to depart from then Costco Travel provides the user suggestions of airports based on the city entered. Also, if there is an error, a pop up box appears in the center of page and suggests a solution while highlighting the location of the error.
 * Writing style is very simple and straightforward, important information for each package has been emphasized with bulletins
 * The menu design is kept very simple, black text on white background. The background changes to blue when the mouse is over the menu and the subcategory expands (if a subcategory exists).

**High-level concepts:**
 * The site is well organized, only a few irrelevant advertisements have been placed on the site,
 * It is obvious that the site has been professionally designed.
 * Besides the professional appearance of the site, they have managed to create a site that is compatible with assistive technology.
 * For example, the decorative images have been implemented so that they could be ignored by assistive technology and thus eliminate confusion for users.
 * Simple navigation menus placed on top of each site
 * The site is completely scure while the user is searching and whenever confidential information is being inputted ( such as costco membership number and password, payment information)
