If you are looking for a cheap hotel in Boston before November, you may want to check out this Groupon Getaway deal featuring the Marriott Copley Place! You can see if your date is available at a decent rate without buying a voucher first.
Rates for the Marriott Copley Place start at $159; however, some dates are a lot more, especially in the fall. Note: I could only find a few $159 rates and they were all for the end of November. However, I did find some decent rates for a few weekend dates (late July for example), which may be a good option when you overlap with a few other deals (see below).
This deal is available for 14 more days or so; however, if you purchase by 5/16/14 you can save 15% (max discount $50) with promo code TOP15 at checkout!
Also, make sure to check out through a cashback website like Ebates or Shop At Home to save 6% and 5% back on your purchase! This would make the hotel room roughly $127 after promo code and Ebates cashback.
