Seattle travel tips

1) Be punctual to get on well with Seattleites

Punctuality is a feature of Seattleites. Try to come everywhere where it’s scheduled on time. Locals will hardly accept the apology even after a slight delay. Please, be punctual!

2) Attend Benaroya Hall, Seattle’s premier art venue

Benaroya Hall is considered to be a premier arts venue in Seattle and host a 2,500-seat audience. It offers a variety of performances and shows annually. Though the Seattle Symphony is the main attraction for visitors, folk performances, concerts, or live shows can also occur. No matter what occasion takes you to Benaroya Hall, you are going to be impressed. Just believe!

3) The Seattle dog is wanted, find and grab it

Wandering along the streets of Seattle, look for a hot-dog stand. Grab the Seattle hot dog with creamy cheese on the top. You must try it! It’s extremely delicious!
