Questions & Answers about kaigi wa muryou to itte mo, yoyaku ga hitsuyou desu.

What does といっても do here?

It’s a fixed expression built from 言う (to say) + て-form + も, meaning “even though (it’s said/called) X; admittedly X, but ….” It downplays or qualifies the first statement and introduces a limit or exception in the second clause.

Why is it 無料といっても and not 無料だといっても?

With nouns/na-adjectives before といっても, the だ is often omitted in this set phrase. Both are grammatical; 無料だといっても is a bit heavier/explicit, while 無料といっても is smoother. Don’t use polite です before といっても; use the plain form.

What does the particle と mean here?

It’s the quotative と, marking what’s “said/called.” Even when no one is literally speaking, it turns the preceding word/clause into the content of “say/call”: X と 言っても ≈ “even though it’s called X.”

Why is は used after 会議 but が after 予約?

• 会議は sets “the meeting/conference” as the topic—the thing being talked about.
• 予約が marks the subject of 必要だ (“to be necessary”), i.e., “a reservation is what’s necessary.”
  If you say 予約は必要です, you add contrast/emphasis to 予約 (“at least the reservation is necessary”), while 予約が必要です simply states the requirement.

Why not 予約を必要です?
