As blues points out, the gathering could be fun depending on your circumstances.
I think the main reason I became a dub was the atmosphere at the assemblies was so unique. I felt like I had found my "herd." This was because I volunteered to work at the first assembly/convention I ever attended and continued to do so for many years. That made the conventions much more palatable.
I worked in the food service operation and toiled long hours at two or three conventions every summer. I never heard a single talk because of all the work we had to do during the sessions in order to get ready to serve during the breaks. When the WTS dropped that arrangement, I had to sit and listen to four days of talks for the first time in my dub life and could not believe how mind-numbing and uncomfortable it was! Right after that, I got "rescued" when an ex-dircuit overseer moved into our congo and became our PO. At the next convention he appointed me to the News Service desk and I got to sit upstairs in the "Most Holy" (executive suites) as part of his team for the next several years.
I had to pay some attention to the program and could hear and see everything and take notes, but there were a lot of distractions, good coffee, outside food and snacks brought in (supposedly for the visiting Bethel speakers and other heavies, but they always brought enough for everyone). And because I was "working," it was easy to relieve the boredom during a dull talk by filling out reports or creating tasks that were more or less related to my assignment. Occasionally, a reporter or news camera team would show up and I'd have to go downstairs and walk them around, answer questions, and so forth. During the breaks upstairs, you met a lot of interesting people and heard a lot of dub lore.
It was only after a new CO came along and, reacting to complaints from elders around the circuit that our congo was dominating the convention assignments and speaking parts, that a new chairman was appointed and other elders began getting those privileges. So for me it was back to the main auditorium where I learned that Karma is, indeed, a bitch.
