I am starting to look into hotel blocks for OOT guests and was wondering if any of you have advice for getting hotel blocks in Baltimore. My ceremony will be at the Baltimore Basicila on Cathedral St. I'm thinking of having two hotel blocks, one right near the Basilica and one in the Inner Harbor. Or should I just stick to one or the other (I'll need 20-30 rooms total)??? And how far in advance do I need to let the hotels know how many rooms I need??? Also, any recommendations for/info about hotels for either location would be great! Thanks!
