One review or two?

I say 1. I think of it as a review of the club, not of the visit.

2 visits would actually make the review more useful. Unfortunately the format only allows you to select one occurence for stuff like day of week, # of dancers, shift...

One and just talk about both visits

Not only that but I think you have to wait a month before submitting a second review of the same club.

^ Yes -- so write one review describing the better or more interesting of the two visits. If you have something to say about the other visit, wait four weeks and write another review.

Just write the review and break it into two paragraphs

Discuss both visits in one review. Give time a day of week etc.
I will give the perspective of tow without wasting the time of the reader.
