I would reach out directly to the tour regarding this question. I do not know if there is storage space in the sprinter van for the walker or the tour's policies. We had a senior on my trip who was able to walk the brief hikes, slowly and still enjoy. Most of the stops are definitely walker accessible but you may require more time than is allotted for the stop to enjoy it properly. We also stopped as Oswald West State Park which would be only stop that may not be manageable using a walker. There is about a 10-15 minute brief hike down to the rock beach but the water and sand beach are inaccessible unless you walk over the rocks which is unrealistic even if assisted. If you can keep up with the pace, you will still be able to enjoy the view but I do no recall any sitting areas. Best of luck!

There are restrooms at multiple stops. The guides will let you know which ones are the best.

You don't need to call, they'll contact you a day or two before your tour. I hope you get Jeri as your guide .

The hotels they pick up at are on the description of the tour. We were picked up at Hotel Kimpton Monaco in Portland. You can call to check if they will pick you up.

Yes it was a small group tour. The van had comfortable seating for 8.
