You remind me of the scenario where a significant other that says "I know I cheated, but I am not going to do it anymore... I love you and want to be with you" and then gets busted over and over.. and you're the person right there enabling them because you focus on what they say, vs what they do.
It has nothing to do with it being tomorrow or next month or six months. Just because they are finally doing something doesn't mean they've changed, or have fixed anything, or even seen the err of their way. It simply means "we've riden this horse into the ground and its dead, so time to get a new horse".
It's the same reason they had HISTA running next door well beyond it's usefulness and did nothing about it.
You're preaching this future upgrade is them emerging from their shell.. and fixing everything.. and keep using the word 'now'. When reality is its something that is going to be probably 16-24m away at best (now? You keep using that word... I do not think it means what you think it means) and is an attraction reboot because freakin 15 years later they face the fact their movie about california doesn't fit everywhere.
We are talking about Disney's attention on show standards and upkeep. Running attractions into the ground and then doing a refurb after they are trashed is NOT upkeep. It's optimizing return.
So the fact Disney is replacing an attraction some months if not years into the future is NO reason to not maintain it for the guests now and until that time. Arguing otherwise is simply following the bone they tossed you and continuing to ignore that show standards are not just about future guests, but EVERY guest.
You do PREVENTATIVE work... you engage plans BEFORE stuff fails or needs replacement... all so you can ensure the highest level of continuity of service for your guests. Not make excuses like "well it will take 2 weeks to get the part" - that's why you buy SPARES so you don't have that downtime. But your argument is 'well they didn't know they'd need it..."
