Thank you, @Christina Zuniga! I'm considering signing up for next week's training, so that is perfect. 
Denee Wilson I just finished the training today, although I couldn't attend yesterday so I missed the nurture section. If you're considering signing up, I'd ask for the agenda from them. They provided me a list of things to go over every day and it really helped me to decide.
CONS
- Some things are barely a step above Foundations training which can be a bit frustrating. For example, I think Foundations includes visibility rules (on Forms) but they went over that which was a bit boring for me.
- The slides were very text heavy, when a lot of it needed visuals to help me understand. A good example is Custom Objects, the trainer was explaining using link type as a unique identifier. This would have really benefited from a visual. I'm still a bit unclear about how to set up the many to many vs. one to many.
- They provide you with a Sandbox instance login, but mine lacked access to a ton of areas even though I was assigned in-class projects to complete that I could not do without access. For example, creating a Custom Object with no access to it in their instance. I just went into my own instance, but it seemed strange to give an assignment and a login, but no way to complete that assignment based on the security level. If I wasn't a current customer with Admin access to my own instance, I wouldn't have been able to try out some of the assignments.
PROS
- If you have no experience with something on the agenda, this can be a great training! I haven't used Snippets before but want to implement them this year. Training on Snippets was awesome! I now have a good grasp on how to do it and ideas on where it could be implemented.
- They start on time. I hate when you log in and they wait 5-10 minutes for other people. The trainer was prompt, checked for questions often and gave specifics on her experience with different items including some interesting advice I hadn't thought of before.
- There were a good number of hands on activities, not just lecture. Especially toward the end of my training, the trainer as answering questions about specific set up from the audience and providing recommendations. It was nice to use her as a sounding board.
I'd say it all has to do with your level of experience specifically around the agenda. If you're unfamiliar / never used those items before, I'd recommend it. If you already know how to set it up and what it does, you might get a few nuggets of advice, but probably not worth the price.
Hope this helped!
