That's sort of my gut feeling. If they are calling ahead of time, my gut says there is a reason and they are trying to avoid some kind of issue when you are actually there. Based on that gut feeling, I'd be inclined to say yes just to avoid spending part of my vacation dealing with whatever the issue is when it could have been taken care of ahead of time.
I'd take the switch. Right now the YC lounge is operating in a temporary location while they make some changes. The temporary lounge is just fine though. However, we got a chance to try out the BC lounge and it was far better than the temporary YC version. I'm guessing that once the permanent YC location is complete it will be pretty much the same as the BC.Also she is not sure we will like BC club level as much as YC.
It was my understanding the YC lounge reopened a little less than a month ago (per the YC/BC official thread). Did they close it again?
We have stayed at both. I will say that our Lagoon View was beautiful at YC. If you like YC, just stick with it.
But, I have never understood why people make such a big deal about distance to X from BC vs. YC. It's a very negligible distance, IMO.
Also, for the people talking about losing a balcony. I know, for a fact, that there is at least one YC CL standard room with NO balcony at all...not even one of those standing ones...there's always the chance of getting that!
