Long overdue holiday- any ideas for stayvaction?

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!

Don’t decorate. DIY decorating expands to fill the time available IMHO. Reading, mild TV watching, meeting friends, sleeping later. All will be relaxing. Like retirement but time limited. ?

Book yourself into a local spa for the day and have a few treatments.
Visit a lovely hotel or cafe that does afternoon tea.
Spend a day binge reading or catching a box set.
