I think that sounds like a good rate. The lowest I have seen them in two years of watching minivans is $199/wk. I got lucky with that rate last January, but I booked about 8 months earlier. You might want to check their last minute specials. I've seen that rate come up periodically.
You don't have to join the Emerald Club to pick your own car. If you specifically rent a minivan, you just got to the minivan aisle and pick whichever minivan you want. They also have the Emerald Aisle, where you reserve a midsize and can choose from any car on the Emerald Aisle. It's guaranteed to be a midsize or larger, and you MIGHT get lucky and find a minivan or SUV. There's a thread titlesd "What's on the Emerald Aisle" or something like that and you can see what people are finding.
If you join the Emerald Club you will get an additional 10% off your reservation and they might send you a coupon by email for $40 off a weekly rental. If you decide to sign up after making your reservation, just call them and give them your Emerald # and they will apply the discount. I you get the coupon after making the reservation, just call and they will apply the coupon, too.
