Illuminations Tour question

[craigindaville.livejournal.com]

My SO and I finally managed to get tickets to the Illuminations tour-- in past years we either missed the date they went on sale, or just couldn't make the tour date(s). I am a hobby photographer and would love to try out some night shots on the tour, but can't find two pieces of information to help guide me in what lens(es) to bring and whether it'll be possible. Hope you guys can help!

1) Are the trolleys the kind that are basically outdoor seating, where everyone kind of sits facing outward (aka like one of the old SF cable cars)? Or are they the kinds that are really just buses with trolley-like exteriors and everyone is inside behind glass?

2) Do the trolleys tend to stop, or at least realllly slow down, at the houses? Or do they more or less just cruise by at a decent clip?

Thanks!
