I like forearm IVs the best. And I second the suggestion that someone else made about shaving your arms beforehand. It has several benefits, not the least of which that the IV is more comfortable coming out, the tape adheres better to your skin (so if you sweat a lot, like I do, it stays on better), there's the idea that there's less chance of infection (not really proven, IIRC) and it's easier to find the vein and get the stick the first time without the hair obscuring it.
If the hospital you're going to doesn't have an IV team, ask for their most successful IV starter (on my floor it was an LPN, she was genius with a catheter) and be assertive about it. You deserve to not be stuck fifty times. Also try to make your veins blossom by putting a warm pack on your arm before they try to start the IV. You can use a heating pad, a towel soaked in hot tap water, etc. Drink lots of water in the days leading to your birth so your blood volume is good.
Oh, and if your IV is uncomfortable, ask them to change it. They'll be resistant, because an IV is a portal of infection, but if you tell them that you'll take it out yourself if they don't change it they'll probably come around.

Be a pain. I love patients who are a nuisance, It makes me pay attention to how I'm doing my job.
