Hi, I also had the £139 package, at about 27 weeks - originally was going just for a gender scan with the "freeview" but then had some long distance visitors travel just for the scan so wanted to make sure that we got the guarenteed retry for the 3D/4D bit if baby wasn't co-operating at first. I did phone before to check what the limit was as I wanted to take 4 other adults with me - the lady said that would be fine for the scanning room but they might not all be able to fit/sit in the reception area when we arrived if it was busy. As it happened we were the only people waiting so it was fine.
We were in the scan room about 30 minutes, got updates on all her measurements, confirmation of gender and ended up with about 12 printed photos and copies on a CD, plus about 15 mins of DVD (3 times as long as they state) at no additional cost - possibly they felt a bit sorry for us as baby was asleep and had her hands over half her face for most of the time! We were all really pleased with the service provided and would recommend it - now just trying to resist booking another one!
