I will give this book 4 stars because it succeeds admirably at being what it wanted: pure "plot what plot" escapism. I don't generally read anthologies or collections of short stories because I always want to dig deeper, and often end up unsatisfied, but I picked this up on the strength of the authors' bodies of work, and it was fun.
It clearly contains lots of sex, in a variety of ways, using a variety of techniques and tools, with a variety of partners. I was very entertained at the descriptions of Radclyffe's spreadsheet, constructed to keep everything straight (as it were). It got a little old to read the book straight through as there isn't much variation to build in to a girl-meets-girl(s)/girls-have-sex scenario, making a one-seating read border on tiresome, but picking it up to read a story or two a day was fun, and it was delightful to meet some old characters from other books again, which helped lend some depth. In addition there were enough spot-on observations about human psychology, and moments of true emotion, that on the whole it succeeds, and I'm curious about what the next vacation scenario (reportedly on the Las Vegas Strip) will give us.
If you're looking for plot or character development, this book will not meet your requirements. But if you're looking for a book that doesn't require much thought as it romps through numerous bedrooms, you should be satisfied (no pun intended).
