Only you know you, and whether your plans would delight or appal others doesn’t matter. What I will say, however, is that there is a huge difference between being off work for a week or two and enjoying ‘chilling’, and seeing it stretch ahead for the rest of your life.
I retired at 57 with a similar pension to you (not as much in savings), and haven’t regretted it. I learnt that I do need some structure, though - as much as I loved pottering when I was working, I was only doing it on a short-term basis, and as a permanent prospect it soon lost its appeal
. It’s easy enough to do something about that, though - I’ve taken courses, joined groups and so on, so I have less ‘time on my hands’, without having to set an alarm. There are things I miss about work, but I do part-time lecturing/consultancy which ‘keeps my hand in’, and keeps me in touch with others in my profession without the stress or responsibility.
On another note, I agree that static caravans are a money pit. We have one, and I love going to it. It’s great having our own things over there, and having the freedom to come and go when we feel like it, but in the past few years the atmosphere on sites has altered because of so-called ‘staycations’ making them very profitable for park owners. They make a fortune from selling new ‘lodges’ (posh caravans!) and will often try to find ways of getting existing owners to leave, so that they can sell their pitch to a new buyer. Contracts usually specify that you have to sell back to the park (or pay them a high percentage of a private sale). You lose tens of thousands if this happens, and there is always a rule that you have to ‘upgrade’ your lodge when it hits a certain age, even if it’s in great condition. Also, rent is expensive (and remember there is also insurance, fuel and various other costs to consider), so you will probably find that you want to get your money’s worth and won’t go elsewhere very often. I would buy one now, unless some sort of legal regulation comes in, as park owners can do as they please as it is. Ours is 5 years old, but we’ve been on the site for 25 years. I’d really miss it after all this time, but financially they are a disaster.
