Many of our cheap, cheap hotels are pretty awful..Recall, one time there was no other hotel left in all of Long Beach..We had to choose a local cheap hotel, that would more likely be thought of as a house of action...Very noisy...Had mirrors on the ceiling..
We had to stay there...Because, we wanted to be very near the harbor to catch a boat at 4...
I would prefer hotels...You go with a group, makes hotels not so pricey...Sharing rooms...I like camping, but after 115 miles of hard climbing, puttting up camp seemed like a chore.Even in the country many of cheap hotels, are really flop houses that might not be safe..But, then camp sites can have unruly people about too.....
You plan to spend $30-$60 a night on Motel 6's...You will probably be safe ...To help organize safe and nice camp sites...Contact "Adventure Cycling" in Montana...They publish a cycling map that helps the touring cyclists to find decent accomdations, whether hotel or camping...I would not travel on bike without it...
Just decide which of their routes you choose , purchase those maps and your trip will much easier and you can ride assured to what the next night will bring..
