I mainly fly out of Terminal 2 and 4 (guess my alliance... ha!), so that's what all my opinions are based on.\n\nTerminal 4 is larger/newer and now has the SkyTrain from the economy parking to it, which is surprisingly more convenient than I though, so maybe it's not a complete waste of money. Although, you still need to take shuttles to the rest of the terminals.\nThe signage is rather clear for the most part, but if you are part of any of the premium boarding groups, sometimes the signs are either not very clear or missing. Seems to have gotten better lately though. Baggage claim area has large screens telling you which carousel has your flight's luggage (foreshadowing for Terminal 2 right here). If you are being picked up by someone, remember that there is both a North and a South side of the arrivals area, so be clear where you are going to be right away, besides just naming the door number.\n\nTerminal 2 should just be a regional airport of its own. It sure got the conveniences of one. The signage for initial security check point is Flight Crews, First class and the rest. Do note, First Class is actually for most Premier flyers and TSA PreCheck as well. Not that anyone can tell you that.\nThe 4 baggage claims carousels (in theory) show the flight number of where the luggage is coming from, but so far it at best displays late, or more often is announced over the speaker and for most fun occasions, on the wrong carousel altogether. At the very least, there is only one side to the terminal, so you don't have to tell North/South to your heat stricken friends when they pick you up.\n\nFood/entertainment choices are nothing exception in either of the terminals and are typical airport food.
