for 6 adults and 6 large suitcases in florida

cant decide what would be better to go for anyone able to shed any light on it ?

We hired a Chrysler Town and Country on a recent visit to New England - very similar (rebadge?) to a Dodge Grand Caravan.

We managed 2 adults, two kids and a baby, three 20kg suitcase, Bugaboo pushchair, plus three lots of hand luggage. There wasn't much space left.

The boot is quite tall but not very wide. Definitely not enough room for six adult's worth of luggage. You might just be able to squeeze three adults on the back seat, fold one of the two middle seats into the floor and get a couple of cases in the passenger compartment.

If you are all good friends and you're not traveling too far with the luggage then you might be OK!

Impressively spritely for a big old girl, though - 280hp V6.

Depending on how far your accommodation is from the airport - I'd get the Grand Caravan/Town and Country and potentially make two trips to get your bags/people to your hotel/house (I refuse to use the word 'villa' - this is Orlando, not ancient Rome). The alternative is to rent a van conversion, but I can't think why anyone would want to spend their vacation bouncing around in one of those monstrosities.

No, no, no - those pass-vans are plain awful. Rent a minivan or a Suburban/Yukon/Escalade and make 2 trips from/to the airport. You'll thank me for this sage advice - unless you enjoy rattling around in a commercial vehicle when you should be enjoying yourself.

Agreed they're nothing special but they are cheap and huge for moving people and luggage around.
Iy depends if you want a 40odd min round trip twice and have someone willing to stay at the car lot waiting for you.

The sense of occasion is lost somewhat, when you roll up at Timpano or the Mall at Millenia, looking like a bunch of Mexican orange-pickers.
Any full size GM SUV with 3rd row seating - or a full-size mini-van will cart six adults around in comfort. The airport run is a pretty insignificant part of the vacation and it just seems daft to saddle yourself with a clunker for the duration, just so you can move your bags easily. I'd suggest it's but a small inconvenience with a big pay-back. If he's staying in Orlando vs Kissimmee, it's a 10-15 minute commute.

well its booked got the tahoe who knows may end up with a suburban suppose it depends what they have when we get there

staying i drive down by convention center again. my parents said they would get a taxi with the luggage if it helps

Worse Case scenario - a couple with luggages grab a hug Cab and go separately ...........

Trim level on something like that will be high, better specced than you would expect over here,

I had the same problem in 2008. We were doing a road trip from SF to Tahoe, Yosemite, Death Valley, Vegas & Grand Canyon South Rim. Having had Caravans & Grand Caravans before, I knew they wouldn't be big enough. Having done some research, I opted for the Sienna. The floor space behind the 3rd row of seats is recessed, and we could get 4 medium size cases stood on their ends in the recessed area, with the remaining 2 laying on top of them (and still see out of the back window).

The Sienna hauled 6 adults plus 6 cases plus hand baggage for nearly 2000 miles in a fortnight. It rode smoothly, handled quite well, may or may not have hit 100mph easily (depending who's reading this), was extremely well-equipped and was big enough that no-one felt like they were wedged in. If Toyota made right-hand drive models I'd buy one!

So my advice would be to not take so much stuff, use mid-sized cases (15-20KG loaded), and get a Sienna.

ETA: I see you've already booked the car, but the above info may be of use to someone else.
