On Disney's mobile site, you can add restaurants for example, to your wish list. And interestingly enough (you will find this in the upper right corner of the page) in the form of a ❤, only it will be white, click on it, and that particular restaurant or ride etc will be added to your wish list. Then go to Things to Do, that's in the menu (Upper left hand corner of each page) and down that list will be your wish list, click on it and you will be taken to that page.
At the bottom of each page you will also find "Show More Links" there you can find the link for your wish list too.
You just need to be signed into your account. If you don't have an account, it's simple and fairly quick to do.
