Hives or Bug Bites?

So I'm staying at a hotel (Home 2 Suites by Hilton) and I woke up to these. I also have two on my forearm and one by my armpit? I've checked the bed for bugs and nothing but the carpet might have something? The shirt I was wearing did fall on the floor so maybe thats it. Looks and feels like mosquito bites but I haven't left the hotel room-_- Anybody had anything similar?
