I have made a reservation for June 29th in Salem VA I will be arriving sometime the morning of the 29th around 3am. I am only staying until around 10 am the same day, will I be able to check in that time of the morning on the 29th

Yes

Wow ! Idk ? Under normal circumstances I'd say yes but if I were you I'd call & tell them about your dilemma just to be on the safe side. Obviously most all hotel's have a front desk attendant 24/7 for situations such as yours but I haven't been up there in yrs & I do know that the ownership switched hands so ? One would certainly think so but stranger things may apply here. Best of luck to you...
