Travel
We booked a block at the hotel mentioned below for 6/4-6/7, got about 15 rooms so there should be plenty of space.
We also recommend getting an AirBnb, especially if y'all will be coming up in groups. There are several in the Portland Metro area and this will provide more flexibility in your budget and time frames and a few of them are even closer to the property in the woods by the river.
If you're a crazy person, you're more than welcome to camp on our property the night of, and any point two days before or after the wedding.
Local folks who are driving, please carpool if you can.
