Hi there!
Thanks so much for your question. As you wait for possible feedback from the community regarding their experiences with hotels, I thought I'd share an article that one of our contributor's shared some time back regarding her experience. While her situation sounds like it may be more extreme that yours (I am speculating), but nonetheless...it may provide you with some thought on what might be triggering these attacks (i.e. lighting, mold, carpeting, cleaning supplies, air room quality, etc.) https://migraine.com/blog/how-to-survive-a-vacation-tip-1-dont-trust-the-website/
Take good care & always feel free to reach out!
