re: Will any science be conducted during the trip?
Oh, some gravometric velocity measurements, atmospheric temperature variants at various altitudes on the Ferris Wheel, impact force parameters of the bumper cars - the usual.
Seriously, if the $100 million tourist isn't up to or interested in conducting any actual science, then I hope the real cosmonaut onboard or automatic instruments will do some real science. They might also consider studying themselves for biological measurements beyond Earth orbit - the first time since 1972.
When we are routinely flying about lunar space like it's an airport, then spaceships can afford to be pure pleasure vessels.
