Hear, hear, phoenix, annsixty and Lona. There's a particularly cringeworthy thread on Mumsnet at the moment where people have been asked how much they have in savings, and some of the bragging and boasting is just awful. Mind you, I did like the one that answered something like "eleventy billion pounds" 
The city break sounds lovely, if you can easily afford it. Likewise theatre tickets or a spa day, with babysitting thrown in. My son would love the idea of the shiny £1 coins, but he certainly wouldn't be getting 500 of them!
