We're going to be in London June 10-15 (but leaving very early on the 15th). My 16 year-old daughter really wanted to see Windsor Castle, but the dates are terrible for us: it's closed completely on the 13th, the state apartments are closed on the 12th and 14th, and St. George's Chapel is closed the 10th-13th. We would go on the 11th, when the state apartments are open, but we wouldn't be able to see the chapel.
I'm wondering if we would be better off seeing Windsor another trip, and maybe doing Hampton Court instead. But, DD really liked the idea of Windsor. How much would we be missing out on without the chapel?
