Travel doesn't get me excited - you're away for a couple of weeks and then you come back and what do you have to show for it? It's the other 50 weeks of the year I'd like to spend any extra money on, making day-to-day life more pleasant.
So I'd rather spend it on a nice home and would be extravagant in making it comfortable and pleasant to live in, easy to clean, easy to get around, even in old age, and attractive from the outside.
I agree with the bedlinen and would also get in professionals to work out the best way to light the house, and also to fit a sound system in the best position with the best quality. If there was any money left over, I might treat myself to a change of decor more often, just because I can!
And I'd chuck out all the pot plants we have now, which are mainly single tall twiggy twigs with a single sad leaf on the top, and get some really bushy green plants which make it look more lush. (Hubbie is in charge of these and he holds on to them, come what may, with no regard for what they look like).
