My hospital wanted a fiver for the photo's, so that must differ.
Definitely take your notes - you can be sure if you don't then they'll want them! (they needed to call me back for another scan and wanted to write on my notes that I had paid for my photos and that I had another appointment due).
Not sure what tips you might be looking for so I will run through everything I can think of:
They'll warm the jelly so its not cold enough to make you squeak when it is applied to your abdomen!!!!
You'll need to pull your clothing down the bikini line and sometimes a bit below (baby lies low in the pelvis at the 12 week scan) so some people find it easier to wear something that is easy/comfortable for you to do this. I was fine in my jeans.
If the baby isn't laying in a good position they might ask you to do star jumps or roll from left to right etc, to try and change the foetal position. This is especially important if you're doing the NT measurements for triple screening. But don't worry, if they can't get all the measurements needed then you'll get called back another time.
Oh and it doesn't seem to matter how you position yourself on the couch - you always get asked to move closer to the edge towards the sonographer!
really well thanks! I thought I was just starting my 14th week but they said I was 16+1!! so that was a bit of a shock...I was counting from the first day of my last period which was in Jan but they said we actuall conceived in Dec! So new due date is sooner than we thought!
We didn't have to pay for the photo's either but the good news is that I don't have to wait too long now til the next scan - we're going to find out the sex too which will be so exciting!
