ISTOCK-TRAVELLAGGIO

Many cities love their sports teams, but Boston takes its fandom to another level. When its squads win big championships — since the turn of the century, Boston’s four major professional teams (the Red Sox, Celtics, Patriots and Bruins) have won 13 titles — there are parades in the streets. Kids skip school and adults play hooky from work to celebrate. And when they lose, the city may as well be in mourning.

Whether it’s the big four pro teams, area colleges and universities (like Harvard and Boston College), annual sporting events (see: April’s Boston Marathon and October’s Head of the Charles Regatta) or major one-off happenings like the upcoming FIFA World Cup, fans show up in a major way.

High-end hotels around town know this, which is why many of them cater to sports fans with all sorts of special perks and amenities. Keep reading for some of the overnight packages we can’t stop cheering for right now.
