What are you looking for? How much do you want to pay?
Give me a few details and I'll soon get you a list. Somewhere like the Jarvis in town (about £80/night), smaller hotels like the Cedars or De Montfort and a few simple B+B. Loughborough doesn't have anything all that special (I recently had someone ask for a 5 star with wireless internet access - he'll be lucky, even if he did once win a Nobel prize), but there is plenty to choose from. For the GCR you can also stay in Rothley or Quorn where there are stations on the line.
