About pets, I have a zooby cat which is really fun, it can wander your land, act as a security system, or you can just hold it, they are very real looking too.
About fun places to visit. I can list a few, "Insilico" is a really cool region, best way I can describe it is "cyberpunk". The region "Deshima" has a really nice region sized space station. If you are into Stargate, the regions "Stargate Command" and "Midway" have nice replicas of the SGC and the Midway Space Station from Stargate. I know I am forgetting a ton of the great places I have found.
You mentioned the space park, I enjoy that one as well, my partner loves it.
