Travel Note
If you will be a ferry rider, make sure to check the ferry schedule just prior to the date. The schedule has been changing, they've been understaffed, and it's also that time of year when more and more people are heading to the peninsula. Make sure to give yourself lots of time, the earlier the better. This link is for Edmonds/Kingston, but you can also take Seattle/Bainbridge, and if you're feeling dangerous you can drive around!
House Or Rental
There are several cabin options nearby. If the casino fills up, or you just don't want to stay at a casino, check out some of the cute accommodations around the area. Kingston is very close to Port Gamble, so is Port Ludlow. Sequim is about a 45 minute drive but also has hotels and I'm sure even more Airbnbs/VRBOs nearby.
