Spend the money you would have spent on a holiday paying someone skilled to do it for you ( unless you really like decorating.) Book an advisor in a big department store and plan a makeover. Go for long walks. Take a train to somewhere (fairly near) you have never been before. Visit a gallery or a museum, and have lunch there. Go to a matinee concert or play. Walk around your neighbourhood, noticing things you are usually too busy to notice: architecture, gardens, shops. Go out early and have breakfast.
Actually, that sounds like my week!
