OP your post will be read with derision by many I suspect. You have no financial plan, you appear not to be terribly financially secure, you plan to quit work and live off your husband's meagre pension and so on.
But only you can decide what's the best for you both. If you are up for it, and can live ok on what you have then go for it. You could let out your house while travelling, there is a small pension and some savings.
Maybe you might need to factor in things like house maintenance, cost of travel, fuel, insurance, HEALTH/TRAVEL insurance (vital), and enough to eat more than a tin of beans, not that there's anything wrong with beans!
Sit down and work it out. Pretend you are staying in your house post your retirement, write every expense down and then translate that to a travel adventure situation.
I retired very early too mid 50s. I did not have a husband or partner, but I owned my house outright, got a substantial redundancy package and a hefty pension, so I am quite financially secure. I would not have done it if I had to live very frugally, but many do and can.
Best of luck.
