Often it is. Request both price estimates to see what works out cheapest for your route; at this group size the difference is often smaller than you'd think.
For day trips usually more than enough; for a trip of several days with lots of luggage a coach is often more comfortable.
Usually not. If it matters to you, put it in your request as a requirement. Then only coach companies with a suitable vehicle will make an offer.
Then you no longer fit in a midibus and it becomes a coach (35 to 66 seats). Pass on a change as early as possible; the arrangement then goes back to the coach company.
That depends on your trip: how far and how long, on which day and in which month. For 30 people we recommend a midibus. Fill in your route and date, and within a minute you see what coach companies charge for your trip.
