Which hotel

Hello Forum,

I'll be attending the Capital Jazz Festival at the Merriweather Post Pavillon in June. I'm attending both concerts on Saturday and Sunday. There's also an afterparty located at the Marriott BWI Airport Hotel (booked). I've narrowed down the hotels with availability to 2. The 4 Points by Sheraton BWI, AND The Hampton Inn-Baltimore Airport.

I know there're other hotels, but believe me, I've called them all. I'd rather be closer to the venue than the afterparty hotel. However, it turns out the options I have are reverse. That being said, which hotel should I choose from the two listed above...pros, cons...

Thanks in advance for your help
