In reply to linal66:
Some on here have way more experience than me, but for what it's worth:
We went to the Dolomites this summer to do VF. We drove there and took our time, via Ghent, Munich and the World Cup final ina bar in Heidelberg. It is a long drive. We camped at Corvara - expensive but lovely toilet block and a superb view! Corvara is a great location for VFs, althopugh in itself it is just a load of ski apartments and tourist shops, with little character, just like the other small towns.
We did the Pisciadu, Piz da Lech (cable car up from Corvara village, then chair lift), the via Trincee (- drive to Arraba, then cable car up - great tunnel, WW1 stuff and view of the Marmolada) and then the Sandro Pertini over in the beautiful national park in the next valley.
These can be crowded, especially the Pisciadu, so get to them early if that bothers you. None were desperately clogged, however, and there was a good atmosphere on all of them.
We did do one other, a little one on the col of the valley on the way out. It was very accessible and so crowded that it wasn't fun.
I had done one VF before, my wife had done none, and we were fine with these. If you did what we did, you wouldn't regret it, trust me - the views are to die for, and the locations constantly amazing. I thought it was an incredibly beautiful place. If you have done any actual rock climbing, it feels absolutely non-scary, whatever the exposure, since the gear is constantly totally bomber. As you approach each start, the verticality of what you are facing makes you apprehensive, but once you are on the routes, they are just a joy.
Next time I would go for more (I think) mountainy routes, like the Posnecker and the Marmolada routes, and try to stay high for more than a day by staying refuges, but for a first go, I think what we did was great
I took advice on here from James Rushforth (have now bought his guide) and Chris the Tall (see his UKC article), but when we there we bought and used the Austrian guide book that was in the Corvara shops.

Don't know what the snow cover will be like in May?
Have a great trip!
