The minivans are as comfortable and easy to drive as a car. However, the luggage space isn't great.
I went to Florida with a group including some keen golfers. We struggled with the mini-vans and switched to a couple of cars.
The Luxury class cars have huge boots. We got 4 samsonite cases and a set of clubs in the boot (plus some holdalls). If there are only five of you, maybe it is worth considering?
