There are lots of places to stay in Windsor & Eton, and most are within 10 minutes walk of the Tango venue. These are a few favourites;
The Christopher Hotel is just around the corner from Baldwin Hall
The Crown & Cushion is 100 yards away, in Eton High Street.
The Prince George Inn is 200 yards away, close to Eton Bridge
The Windsor Travelodge is 10 minutes walk from the Tango venue. But it doesn’t have a car park, and is more expensive. Beware that some rooms face the local nightclubs, and can be noisy late at night.
Charles House guesthouse is a few minutes walk away on a busy road, but with PIN entry, so you can come and go as you please.
