Is it possible to stay in a hotel or Band B for $150 or less? We are seniors. Comfort and cleanliness are important also not a lot of stairs. If anyone knows how to find such a place in Cambridge we would love to hear about it.
Rick only lists two accommodations in Cambridge because he thinks of it more as a daytrip from London. This one has some standard doubles at 114 pounds: http://www.lensfieldhotel.co.uk/accommodation/. I'm confident that www.booking.com could turn up something a little cheaper. The Travelodge chain also has a location in Cambridge.
Premier Inns has a Cambridge location just off the A14 at Junction 32 . Very convenient if you are driving . Leave the car in the car park and take the local bus into town ( 10 to 15 minutes ) . The Bus stop is in front of the hotel . here are several other locations as well , details here http://www.premierinn.com/gb/en/search.html?searchModel.searchTerm=Cambridge&LOCATION=52.20754,0.12404&ARRdd=17&ARRmm=03&ARRyyyy=2016&NIGHTS=1&ROOMS=1&ADULT1=1&CHILD1=0&COT1=0&INTTYP1=DB&SID=4
