At what point did you go to the hospital?

I decided to go when contractions were 7min apart, but this was because I was out of town. By the time I arrived at the hospital things were 5mins apart. Labour started for me at 15min apart. I couldn't talk when the contractions came, and nor could I walk (got stuck in e.d. automatic doors as a contraction hit and I was paralysed lol). My waters didn't break until I was well underway.

I think I also depends how far you are from the hospital, Mine were 4mins apart lasting 45secs and not very painful, but we live 20 mins away so we headed on in. I could tell when we arrived that they didn't think I was in enough pain (and I was only 4cm)so were all ready to send me home after a CTG, thankfully 1 1/2 hrs of monitoring later and I was 9 cm, so that was sweet.
Definately be aware that your second will most likely be faster, so you probably will be better safe than sorry if you go in earlier, just ring your MW, they tend to be pretty good at guiding.

2nd time round was alot faster for me aswell...my waters broke just over 4 weeks early so I had to go to the hospital from the start as I needed antibiotics and I was attempting a VBAC. I was having contractions (so the monitor said) but if I was at home and my waters hadn't gone I wouldn't have had any idea I was in early labour as they just felt like braxton hicks. I was 5cm dilated at the time. The monitor was showing contractions irregular about ever 10-20mins apart It wasn't until another pocket of waters were broken that my contractions immediatley started hurting me and went from irregular to about 7 mins apart for a few contractions and at this point at if at home I would of thought something was up and probably hung around at home for a while thinking I had a bit of time up my sleeve and i'd just do it there for a while, if that was the case though I would of well and truely had DD at home (or in the car on the way to the hospital) as pretty soon after a few 7 minute apart contractions they were rolling contractions and she was born 1 hour and 20 minutes after those waters went with less than 5 minutes pushing.
So i'd definatley go when you feel you need to, even if it is a bit early as things can step up to that next level so quickly.

My MW told me to expect labour to be half as long (short)second time around.
I was worried about the timing too but thankfully my mum took time off work around when i was due and came to stay out here (we live an hour away from the hospital).
My contractions were only 5 mins apart and really not that sore but DD1 was starting to get worried about me so we decided to leave (was 9cm when i got to hospital so turned out okay. )
