Tent Rentals for a Bridal Shower

Hi Gals,
Just wondering if anybody has rented tents before. I am in the process of renting one and was wondering if Frame Tents are much nicer than pole tents since there is a difference in price and I would be saving some $ getting the pole tent. I also want it to look nice, though.
Any thoughts?
Thanks
Gaby
PS Any weather predictions for next Saturday? All this rain is scaring me!!
