I've been to several events that was organized for trans people and allies. The very first time I attended a trans meeting which was the part of a monthly series of meetings. Each meeting has a central topic which is discussed at the first part of the day, often guest speakers are invited like surgeons, psychologists or other specialists. It is very informative.
At the second part of these meetings we can freely discuss what is on our mind and share stories. It is great to be with people who are in the same or similar situation as me.
When I was new at the group they welcomed me with open arms, everyone was wonderful.
After the meetings most of the time the group gets together at an LGBT club and we have a wonderful night partying till the morning. I'm not much of party-girl myself but I still have a great time.
After my first meeting I attended all the trans meetings I could go to, I met a lot of great people over the years. Of course there are a few bad apples at some meetings but they are always dealt with
The organizers later started organizing picnics and tours too. I have attended almost all of them, and again, it was a great experience.
When we moved the capital city with my girlfriend we helped in the organization of a few tours and parties ourselves.
Nowadays we have a little meeting every Wednesday and we help in small things when we can but our lives got much busier since we both got work so we are not as active in the trans community as we used be.
All in all I recommend attending events, you may find a lot of people who you can relate to and form new friendships but all events are as good as the people attending, so you have to see it for yourself if it is for you or not.
