Guidelines for "reasonable" attorney fees?

Do federal courts for awarding fees and deciding what is reasonable?

So, if there is a 1 hour hearing in court, but 5 lawyers show up and travel from all over the country, can you ask for the full cost of all that, including travel and lodging?

Lively in particular had like 8 partner level attorneys working on things - I wouldn't be surprised if she asks for upwards of $2million (Leslie Sloan asked for $1.2 million, so at least that, but Blake also had all that 47.1 work).

How will a court decide what portion of that is reasonable?
