Renting an RV in South Florida, recommendations

We have space reserved at John Pennekamp for next December. My GF and I will be on one site in our TT. My daughter, son-n-law and grandson want to join us. Our TT is just too small for all. We have reserved 2 sites but only have one RV. They will be flying into either Miami or Ft Lauderdale from Jax fl. and want to pick up a small self contained RV near the airport ( prob will be Ft Lauderdale ) to rent for the week.

Anyway she has found cruise America and their prices are not bad. Just wondering if anyone has other suggestions for rentals in that area. They want a 25' +/- cab over type unit. Will be for 1 week. Driving only from pickup to JPSP and return to same spot as they are flying to another destination after our time together.

Thanks
