I don't think TDS's ride count is bad at all. Before Fantasy Springs they're at 20 rides. And basically every land has a major show. TDS has done a good job overall of expanding on a lower (15) opening ride count, though 3 of them are transport rides, and 4 more were kiddy flat rides. Adding stuff like Raging Spirits (which sucks, but it was a major addition), Tower of Terror, Aladdin's Carpets, TSMM, Soarin', and now Fantasy Springs over the years has been a decent haul for an already good park. I'd hope Comcast is more aggressive than that with EU, but it wouldn't be the worst park to emulate an expansion strategy off of.
