I had a port and it made things a hell of lot easier. There was never an issue with getting set up for chemo and/or blood work (one less thing to worry about). You hardly feel the prick and if you numb the area even that is gone. As far as maintenance is concerned, they will flush it out every time they use it and that should be all that is required. (assuming you do this weekly). I got chemo weekly as opposed for 3 times. If you have good veins and you are only getting a few chemo tx you might get away without it. Of course that assumes that everything is going fine and that you do not need extra infusions such as hydration... all of which are a snap with the port.
BTW removal is also not a big deal (10 minutes).
