Hi there,
Great to hear you're going to be joining us at bath - I know its annoying having to change your plans from online to hybrid, but hopefully this will give you the chance to immerse yourself in campus life and give your time here another dimension.
In terms of Travelodges, there is Bath City Centre, Bath Waterside and Bath Central which are all good choices. Premier inn also have a place in Bath City Centre, and you could also stay at the YHA near Bath city centre - all of these are pretty budget friendly, can do bookings for 1-2 days at very short notice if you need it and have onsite parking.
Do you have anyone from your course/the uni who lives close by? Would there be a possibility of staying with a friend?
Hoping this helps a bit - best of luck 🙂
