Cambridge: leave time for the city itself
Choose Cambridge when the university-city setting is the main reason to travel. University Arms on Regent Street is one concrete hotel comparison, with the centre as the focus of the evening. Pick the museum, college visit or river activity you most want, then check that particular operator or venue. The pleasure of staying overnight is having time between those plans, rather than fitting the city around trips elsewhere.
Good for: A first Cambridge visit, cultural weekends and a city break for two.
Before you choose: College access and activities have their own arrangements. A central bedroom is not a guarantee of admission, a river view or an effortless route from the railway station.
Ely: a cathedral city at a gentler scale
Ely works when you would rather concentrate on the cathedral area and the riverside than build every day around Cambridge. Poets House is a St Marys Street hotel example near the historic centre. Think about how often you want to return to the room and which part of the city you want around you at dinner. This is a stay with its own purpose, not simply a remote Cambridge hotel.
Good for: A compact cathedral-city break with room for a riverside morning.
Before you choose: The cathedral area and the lower riverside are distinct parts of the visit. Check the luggage route and the bedroom bathroom layout; a striking bath can be less useful than privacy or a particular shower.
Peterborough: city centre plus a planned Nene day
Peterborough provides a third city base with its own cathedral and central streets. The Bull on Westgate is the town-centre hotel to compare. If the Nene landscape or an attraction outside the centre matters, choose the destination and transport before reserving the room. Keeping the first evening local helps separate the practical city arrival from a full outing the following day.
Good for: Visitors with a Peterborough event, cathedral visit or specific Nene-side plan.
Before you choose: The wider landscape is not all within a short walk of a central hotel. The Bull has no lift, so a ground-floor request and its confirmation may matter more than a larger room category.
