Gift Voucher Help

[Bonitalazenia]

My Step-Father is very soon to celebrate his 70th Birthday. He is very much loved and my siblings wish to give him (and by default our Mum) £500 to spend towards a lovely weekend in London. Seems a bit vulgar to give the cash £20 notes in a card. They obviously would need a hotel and they love culture, the arts, theatre, food etc....
Any ideas how to present this gift?

[Pleaseuniverseplease]

Could you not book a luxurious hotel and pay for afternoon tea somewhere prestigious and present the vouchers in a lovely gift box?
