What do I do with a gift card for the RAH worth £350

[sophieschoices]

We were unable to attend concerts in the RAH recently due to illness.
The RAH would not refund ticket money but offered us a voucher for the full value.
We are in Ireland and we're only travelling to the UK to see the artist. We won't be going again any time soon. Any suggestion as to how to sell them on or use them? We have no family or friends on the UK that would be interested in them.
Any ideas welcome thanks !

Just find something else you’d like to see and go watch it surely?

Or just offer it for sale... For dunno 250£?

At least you'd get some money returned?

Or tweet the RAH?

Sometimes organisations suddenly find a reason to bend their rules.

It's grim they haven't being illness is the reason.

Are you covered on any insurances?

I'm in Ireland. We were travelling specifically for these concerts and have no interest in any others tbh.
Where could I see the gift card . Any sites that specialise in this area?

Can you sell it on ebay for a little bit cheaper? I come across all sorts of vouchers there...

The OP is in Ireland and has said they won't be travelling to the UK again anytime soon, so not as simple as just find something and go and watch it, they'd need to book flights/ferries, accommodation, possible time off work, be able to afford all of that and actually want to spend the time and money.
