How to know I have slept in too many different places recently

I awoke suddenly last night around 2 am with the nagging sense that I needed to use the toilet but I couldn't identify where I was.

I got up and headed towards a door I thought would lead me out of the room and hopefully down a hall to find a toilet.

Off I went, through the door, but instead of a hall, it was a small room. Very confused I found a light switch, turned it on, and it took me a moment to realize I was standing in my washroom.

Nice.
Too many toilets in too many days.
