The one at Hartlebury would be the better option really .. not as noisy, and will definitely be very modern .. as long as you can put up with a Little Chef everynight. The nearest Holiday Express is Droitwich, and ... they charge you for parking !!
Don't know what type of person you are Mani, but if you enjoy a little mothering then a B & B probably the best option .. just have to google a little, for example, look at the Garden Cottage on this site .. sounds lovely :-
Garden Cottages, Worcester - GBStay
Could probably get a good deal too for 12 nights.
