When our kids were little and we used to visit kid friendly places, we noticed lots of adults visiting without kids. From castles, to theme parks to Disney. Not just the younger generation (pre kids) but middle aged people like we are now.
We would question why on earth someone who is child free would choose to go somewhere full of kids when they don't have kids with them. When we were child free, after household chores, we chose the pub, visited friends and did the grown up shopping ie B&Q, Ikea etc.
We've always avoided doing things on bank holiday weekends and avoided the UK during the summer holidays when the kids were still at home and since they've left home we've gone places on week days and travelled outside of the school holidays.
However I'm now working in a school so now we're limited to weekends, evenings and holidays to go places. We visited West Wales over the Easter Weekend, went to a family fun day in the park over May Day and visited the RHS Spring Festival. We're going camping the week of the Jubilee, but will hopefully be in Australia for the main summer holidays.
Since the kids have left home, we've had spa days, private beach days, been out for brunch, had a game of crazy golf, been to tourist attractions, been to firework display's and seen laser shows and more recently joined our neighbours and friends with their children for Christmas light and garden shows as well as visiting indoor and outdoor play centres as well as soft play for dogs. I've taken Bob to the Lavender fields and Pumpkin Patch, been on doggy play dates and even attended Valentines events and taken Bob to see Santa more than once as well as hold birthday parties for the cat and the dog.
We do however, do things with our kids still, road trips, parties, shopping and meals, but these days they have their children with them and we can sit back, relax and just enjoy being out with them now and not having to take charge.
