I only ever staycation as, outside of work, I have a great lifestyle.
Generally most important thing to me is not to be rushed. Every day at work, I get up really early, rush out to the horse, rush through my time with him, get home, go to work, get home at night. ICK! On holidays, I never set the alarm, I make plans to see people I haven't seen in a bit, go to shops I'm too busy to get to normally and mist importantly, never rush. Get up, sit on the couch enjoying a coffee from my coffee machine, maybe have a second. Spend a leisurely morning with the horse. Do something of an afternoon.
I had 3 months off work when I got my puppy. First month revolved around puppy and what he needed. Second month, I painted the entire inside of my house, ceilings included. Didn't rush. Allowed a week per area, which equated to a couple of hours a day. Third month just rested and started preparing dogs for me going to work.
You can plan day trips to the touristy sites. You probably avoid them a bit normally. You can google to see what's on in your local area.
