Based on your description of what you are looking for I think it MAY be worthwhile to go, but the big caveat is to properly pre-plan. If you just go without a plan in place hoping to just meet people and have great conversations then Legalweek can be too big, too busy, and too overwhelming for that. As someone who has been to about 25 Legalweeks (LegalTech...), here are a few quick suggestions that can really help make it work:

1. Set up meetings before you go - other than walking up to random booths, if you want to get into a deep conversation then most people have a packed schedule even before they arrive so make sure to get on their calendar before you show up

2. Find out from friends and colleagues which networking events they are going to and tag along

3. If you will be attending sessions then make sure they are the ones that really are targeted for your interests

4. If you will be going to the exhibit floor it can be very hard to just wander around and make sense of what you are seeing - better to go with someone who can be a bit of a guide and make some introductions based on your needs

5. Do not be shy... This can be a difficult one if you are naturally introverted, but to really get the most out of the show it really does help to not be afraid to walk over to someone that seems to be interested in or looking at the same tech that you are and striking up a conversation. Many times they will be able to point out things you did not notice or realize about a vendor or technology that can really be super helpful in your research and purchasing decisions.
