I need to go to Boston to take placement exams for the college I'll be attending, and I was wondering if there's any hotels that let you make reservations if you're 18. I've e-mailed a few (Doubletree Guest Suites Boston lets you, but there's no T stop near it), but so far, I'm not having any luck. I'm waiting on a response from Club Quarters Boston about their minimum age. Anyways, are there any other hotels that will let me make reservations if I'm 18 (Brookline or Cambridge is ok, too)? There won't be anyone else with me - no parents/friends, and I do have a credit card. The hotels would need to be accessible by the T (I'd be coming into South Station on Greyhound and taking the Green Line to the MFA stop the next day, but I'm familiar enough with the T to get around) because I won't have a car or anything. Thanks! :)
