Hi all, first time poster so please go easy on me…

Keeping my Gold card will be extremely beneficial for me in the next 12 months, and so I would hate to see my 1000 points go to waste.
Changing my address to Europe is not an option for various reasons.
I have no business trips planed from now until May 10th which is when my year ends.

Without going into whether it is actually worth spending this money or not, has anyone got any creative ideas as to how I can accumulate 500 tier points spending no more then £800-£1000?
I’m based in London if that helps.

Any ideas would be most welcome!!!
