Is there christmas caroling a long the River walk the weekend of December 22nd?

I am not sure. Check San Antonio's web page

I concur with everyone.

Yes I believe there is.

Yes should be very nice

I'm not sure..my vacation of San Antonio was over right after this Thanksgiving

Yes, they'll be floating on the boats doing it. The last night is the 22nd though. They will be floating around from 615PM to 915PM. Its hit or miss though, because its people who pay to ride the boat and sing. Sometimes they aren't the greatest.
