National - Best Emerald Executive location in New England?

I am going on a road trip at end of May in New England. I am EE and reserved a full size car planning to swap at a ES location on Memorial Day Friday night. Which one would be my best choice?
Hartford, CT
Boston, MA
Manchester, NH

Thanks

The MHT location is small. I've never found more than 10-12 cars on Exec Selection and the Luxury and Premium 'rows' can be just one or two cars each.

Without a doubt, BOS has the largest inventory.

Not on your list, but PVD always seems to have a nice and varied selection.
