Flight
Eugene has a regional airport that is convenient. Portland may have more flight options, depending on your point of origin, but it is about 120 miles North. Trains and buses run frequently, just adding a bit of time to the adventure.
Train
If you fly into Portland, it is pretty easy to take a train down to Eugene. The train station is convenient to downtown and hotels, and saves you a 2 hour drive down I-5.

Travel Note
Eugene has cab services, but it is nothing like NYC where hailing a cab is second nature. If you don't have a personal vehicle, ride share services (like Lyft) will be your second best bet. Making friends with someone who has a personal vehicle is your most sociable option.
Hotel
This is one of our recommended hotels. It is close to the University and major throughways, pet friendly, walkable access to the river path, next to Track Town Pizza, and Kate walks past it every day on her way to work.
