I have toured for 45 years. Over the past 10 years, I use hotels more and more so have probably stayed in a hotel 200+ rooms nights over the past decade or so. A lot of this is that there are fewer campgrounds out there and many of the campgrounds that do exist do not accept tents. I do not count the plethora of permanent communities of RVs as campgrounds as to me, a campground should be more from transient (temporary) campers.
In my 45 years, I have had a hotel refuse to accommodate my bike less than a handful of times so maybe 2% of the time (5 divided by 200).
If they do not want the bike in my room (maybe 10% of the time), I ask about or they offer a storage room, unused conference room, or once the main lobby. Basically, somewhere secure due to the value of the bike. As a side note, it is not uncommon to see take off work boots, motorcycle boots, etc. before entering room signs in the lobby of hotel in areas where I guess a lot of dirty boots occur. No common but not uncommon either.
I have always taken care to keep the bike from dirtying up the room to prevent the hotel from having a valid reason to refuse bikes. If it has been raining, I ask for a couple of dirty towels to keep under the bike while it drips.
These observations occur regardless of the hotel's "quality". I traveled a lot for work and am a lifetime top-tier status at 5 national chains (high end to mid-level range) so I rarely have to pay for a hotel at them due to the bazillion points I accumulated while working. However, in places that require what I think are too many points or in most small towns in North America that don't have a Marriott, Holiday Inn, etc., I pay at the small independent hotels. They and the franchised properties are the ones that seem to initially raise an eyebrow toward a bike but have almost always agreed after some polite discussion/compromise.
Overall, I do not think you will have an issue.
