There is almost so much going on it is difficult to find enough time to attend every session that is of interest.
The challenge is if your interest falls in multiple areas.. then more often than not the in-depth sessions will have conflicts.
VMware PEX (Partner Exchange) is a much different venue than VMWorld.
It isn’t that the topics are that much different. There are core areas: Virtualization, EUC, BCDR, SDDCU, Hybrid Clouds,
But hands on opportunity to talk to engineering staff and product management. You never know who you run into.
* Of course there are discounted exams, hands on training, Networking opportunities etc.
