What are these, do you think? I'm hoping for the Westin for the 4*, or the Hilton/Sheraton for the 3.5*, but there's a convention in that area that weekend, and so I don't know if it would be different hotels. Please advise ASAP so I can get a room. :) Back Bay - Copley Square area Hotel - $113 4* Bed choice - Non-smoking - Fitness Center - Spa - Restaurant - Business Center - High Speed Internet Access Back Bay - Copley Square area Hotel - $127 3.5* Boutique - Non-smoking - Fitness Center - Restaurants - High Speed Internet Access Thank you very much for your help!
