I've been to both. SafeCo is fantastic like almost all of the "new" ballparks. We sat in right field in either the last or second to last row of the upper deck, and I felt like the view of the field was still very good. But also like most of the newer parks, there are any one of a number of places to see the game from places other than your seats. I'd suggest a lap around the main concourse before deciding on food as there are lots and lots of options. As for Oakland, it might be interesting to try and find the time machine that transports you back in time several decades, but I've never found it. You'll see lots o' concrete and....well, that. The best thing I found there? A security guy near our seats was named Jack Tatum (not THE Jack Tatum, but he pulled out his driver's license to prove it was his name). Not sure about the ticket situation and getting from upper to lower level, but I can't imagine that would be a problem. For that matter, I wouldn't think it would be tough to get something plenty cheap in the lower bowl.
