Walking around this place is an adventure in and of itself. Many fans argue that it's better than Yankee Stadium but I think the verdict is still out on that.
Section 319 was a no brainer and had a great panoramic view of both sides of the field. Equally close to everything and the private feel made the experience even better. I could go to the restroom and concessions without having to worry about long lines and dodging other Met fans. If you want to sit here, you'll need to pay above face value for them online or know someone who can get you tickets for them. You won't be able to order these from the Mets website or by calling their ticket office because they're always sold out.

We come to 3 or 4 Mets games each season as a family, always sitting in different spots and section 319 thus far has been my favorite. I love the exclusiveness of sitting in a club section and not with hundreds of other fans in a section that has 100 steps to climb up and down between innings.
I would strongly recommend taking public transportation to Citi Field. You can get on the 7 Train at Penn Station in downtown Manhattan and ride it to Willet Point for usually less than $12 round trip. The train and bus fares are constantly changing so I'm not sure exactly what you'll pay but it's cheaper than driving and parking at Citi Field.
