First, let me echo the welcome to MB! We just got back on Monday and did that exact type of trip.
First, we stayed for 3 nights at the Hard Rock at Universal. While I agree that two days is enough(one in each park), the Hard Rock has a great pool and we spent the third day relaxing and enjoying it. Also, the room key gave us Universal Express, which, IMHO, completely blows FastPass away. So, while Disney has Magical Express, it does not have anything that compares to Universal Express - it's awesome to never have to wait in line. Then, we spent 8 nights at Beach Club and spent one of our days in that pool, too, which, again IMHO, is the best pool the Mouse has to offer. We could have used ME for the return trip to the airport, but Quicksilver is comfortable, personal and affordable. And, they offer a stop at a supermarket which you cannot get with ME. All that for only $155 for all three rides combined (airport-HardRock-Beach Club-airport) in a luxury Town Car. That's they way to go, for sure
