£30k divided into 365 = £82 a night
that's not 'luxury hotels'
you'd be lucky to get a premier inn in most of the country
and it leaves absolutely nothing left over
Bear in mind you won't have any facilities for cooking so will need to budget at a minimum £15 for food (and that is literally the absolute cheapest I could think of getting 3 meals a day: a croissant from tesco for breakfast, £1 sandwich £4)for lunch, £10 dinner at wetherspoons. That's with no snacks, and drinking only water from the hotel bathroom tap!
That's down to £67 a night
Hotel rooms at that level don't have a fridge so you won't even be able to make yourself a cup of tea with fresh milk or anything.
And that's without buying ANYTHING ELSE, ever,for the rest of your life. No foods, no meals or drinks out with acquaintances, no bottle of wine, never getting the bus or train anywhere other than the affordable town you've moved to, no elderly-approved exercise like bowls or golf or swimming, no clothes, no books, no netflix, no presents....
Sounds miserable tbh and far from the 'luxury' lifestyle you are looking forward to, stuck in a travelodge in Grimsby, having to wonder every day if you can afford to treat yourself to a cup of tea.
And obviously all the above are at todays prices, and assuming your pension keeps up with inflation and the cost of basic goods and services.
