Is this a bed bug? I found it crawling on me in hotel bed
As already stated in the comments the animal you found is a tick (Wikipedia).

Since they are known to carry diseases you should make sure you have not been bitten or even still have one sucking your blood. So search your body. If you happen to find one still attached, do NOT squeeze it as this may stimulate fluids to flow from the tick into your body (bad). Instead get it out asap using tweezers or even better specialized tools. If you can't do it yourself ask another person preferably a doctor.

If you have been bitten watch for symtoms of an infection such as a red circle. If in doubt always see a doctor since you might require antibiotic treatment.

NOTE: usually nothing happens so don't worry too much but be alert for changes in skin around bites (if bitten that is).

EDIT: since hotel beds are not a typycal habitat of ticks you probably carried it there yourself.
