Seattle travel tips
Seattle hosts the tallest ferris wheel on the whole West Coast. It’s a great chance to observe Elliott Bay at its finest. The wheel is equipped with half a million LED lights and offers a light show every Friday, Saturday, and Sunday from 10 p.m. Private dining with a view is also available, for extra money, sure thing. Make your Seattle Great Wheel experience bright!
Never jaywalk in Seattle. Otherwise, you will get a fine. Moreover, everyone will figure out that you are an alien here. Act as locals do. Cross the street when it’s your turn. Take care!
