Orlando Car Hire - Tahoe or Suburban

[London GT3]

I am travelling to Orlando in May. We are a party of 5 adults with lots of luggage (but only carrying luggage to and from our villa).

Looking at hiring either a Chevrolet Tahoe or Chevrolet Suburban. The Suburban appears to have more boot space but looks enormous. Any advice based on experience?

Also, SIXT offer the best deals via Holiday Autos website but they are off the terminal. Any experiences of SIXT? Do they use new or old cars?

Any other recommendations welcome.

Thank you
