We have an extra day this trip, not sure how we did that, but with our 10day Park Hopper we have an 11th day in Orlando and nothing booked. We thought about Seaworld since we haven't been there since 2006 and our DD4 hasn't seen it yet. So my question is should we rent a car or just take a cab? We're staying at POFQ the whole trip. Haven't rented a car at Disney before, actually haven't had a rental car since 1997 when we won a trip to WDW and it included a Mini Van. Any tips would help, such as who has the best service or cheapest booster seat etc. Thanks in advance.
