Just checked on RailEurope (is there a better place to get tickets ahead of time)

Costs to me for 2 reservations are:

$120 - London to Paris (2nd class)
??? - Paris to Geneva (wouldn't let me book online)
??? - Geneva to Florence (they are emailing me quote on price of sleeper)
$38 - Florence to Rome
$38 - Rome to Venice
$38 - Venice to Milan

I'm more than likely going to make all reservations ahead of time due to the fact I have hotel reservations set in each place (and an important flight back home from Milan). Are the prices above reasonable, or are there better places to order from?

Thanks again!
