Flight
There is only one airport in Boise and while it says it is a medium-sized airport, it is actually a small airport so no worries about getting lost in there.
Train
This is a pretty reliable bus that can get you from the airport to anywhere in Boise. It costs $1.50 for one-way and $2.50 for an all-day pass.
House Or Rental
AirBnB is a great way to stay in a local place and be closer to some fun, "Boisean" hot spots. Prices vary from $60 to $120 per night.
Hotel
This is a nearby hotel that is also in the heart of downtown and can make for an easy way to sight-see whilst being nearby the party venue.
