Bed bugs
I stayed at the Holiday Inn in Santa Monica the last week of August (4th floor). The last night of my stay, I woke up around 2am, got up for a minute, when I came back to bed, there was a small brown bug crawling on my bed. I grabbed a tissue and walked back into the bathroom to flush it. When I came back out, I noticed a larger dark brown bug crawling on the other bed. Same process. And same result - I sat on my bed and watched one, then two small brown bugs crawl out and onto the sheets. Then two more. And another larger bug. I called the front desk and asked them to move me to a different room immediately. They did. A few days after I returned home, I woke up covered in bites. They were odd bites, grouped in threes (which I found out is a bed bug calling card), and really itchy. Doing some research, I learned that these are signs of bedbug bites and the pictures I found matched the bugs I saw in the room. I arranged for an exterminator to come look; I actually caught two of the bugs for her to look at (one small one, one bigger one). The exterminator confirmed that they were indeed bed bugs, the baby and adult versions. I was bitten every few nights until the exterminator was able to complete the treatment. Given that I saw the bugs in the hotel room and I know I didn't bring them in (no prior recent travel and no bug bites in the week before I stayed there, with the bites being so bad that I would have known if I had them before), the bugs came from this hotel. Given the reaction I received from the hotel ("oh, gee, that's too bad") I don't know if they have checked the room or had an exterminator in to get rid of the bugs.
