Please help us in one last family memory

I have run out options for my cancer. I have been told I have weeks to live and would like to make one last memory for my children on a day trip to London. I understand the timing isn't great and that everyone is finding a bit tight at the moment. I didn't realise that end of care would be so expensive and I also don't know how many weeks I have, all I do know is that my health is deteriorating very quickly.

I just would like my children would have one last happy memory where we can forget palliative care and just enjoy a day to see St Pauls, the London dungeons. I need help with moving around London and will not be able to manage the underground.

I don't have time to save due to health and I have costs with funeral etc. I understand if you are unable to help, but thank you for reading and if you don't mind sharing to others.

I would just like to thank you again for reading and anyone who knows me will know this has taken me alot to ask for help as I never do and I feel really shameful for begging.

thank you for taking your time.
