... the best part has being together as a family again.

"I’m having a great holiday season in Turkey with my family! We’ve spent time in both Istanbul and Ankara, but the best part has being together as a family again.” --- AIT Director Oudkirk

1. Should it be "been"?

2. Does the green part suggest that to Oudkirk, being together as a family again is greater than taking a trip itself in Turkey?

 

[Tarheel]

1. In my opinion "been" is missing, and it should be before "being".

2. Yes. More important than the trip is being together as a family.

 

[emsr2d2]

It should be "... the best part has been being together as a family".

What has the best part been?
[The best part has been] being together as a family.

 

[kadioguy]

a. The best part has been being together as a family.
b. The best part is being together as a family.

Why did the writer use (a)? What does (a) mean, as opposed to (b), in this case?

Does (a) mean something like this?

(Until now) We’ve spent time in both Istanbul and Ankara, but (until now) the best part has being together as a family again.

 

[emsr2d2]

a. The best part has been being together as a family.
b. The best part is being together as a family.

Using (a) leaves open the possibility that some part of the rest of the festivities might be better than the family being together so yes, your "Until now" understanding is correct. Using (b) refers only to the current situation, and could also be used to express a general fact - the speaker thinks that the best of part of every holiday season is being with family.

He probably meant to write '... but the best part was being together as a family again".

If you don't mind, could you tell me why it is "some part" rather than "some parts"?

Does "part" here mean "used with singular nouns to refer to a person, place, thing or time that is not known or not identified, as in There must be some mistake"?

Yes, "some" there means "an unspecified".
