This area contains some of England's most popular destinations, and it's best to avoid weekends in the busier areas of the Cotswolds. During the week, even in summer, you may hardly see a soul in the more remote spots. Bath is particularly congested in summer, when students flock to its language schools. On the other hand, Cheltenham is a relatively workaday place that can absorb many tour buses comfortably.
Book your room well ahead if you visit during the two weeks in May and June when the Bath International Music Festival hits town, or if you visit Cheltenham during the National Hunt Festival (horse racing) in mid-March. Note that the private properties of Hidcote Manor, Snowshill Manor, and Sudeley Castle close in winter; Hidcote Manor Garden is at its best in spring and fall.
