How do I tell people

Would it be selfish to tell people I plan to kms in a month? I am giving life one last chance and for a month I am just going to be doing all the crazy expensive shit which I would've otherwise not do like go to a Michelin star restaurant or going to a theme park for 2 nights.

But how tf do I get people to want to do stuff with me? Like I don't want to do all this stuff alone, but most people just think "another time" when they do not realise there might not be another fucking time. I don't want to manipulate and guilt-trip people into doing stuff with me and cause them to freak out. But at the same time, I don't want them to regret not doing stuff with me if I do die because "they're too busy with irrelevant X" or some other silly excuse which does not really make sense even if I offer to pay. I just want them to appreciate their presence for some of my final moment and same other way round.

Idk such a weird conundrum to be in and wonder if there is a solution.(probably not)
