Stay in the hotel 4/22 through 4/25. Now have bites on arm, neck and back.

Spent two nights 9/30 and 9/31. The first night had a few bites, but the next night I couldn't sleep because of more bites and itching. We got up and left. The bites are very itchy and are in the typical line, as in breakfast, lunch and dinner.
I don't know if I'll ever be able to stay in a hotel again.
