Visiting a synagogue advice

[Reuven]

and above all, relax, enjoy, drink it all in. I think you’ll find it’s all good.

I haven't visited the synagogue yet, but I plan to in the next couple of weeks. I read a story by a women who married a Jewish man and later converted. She talked about her experience visiting a synagogue for the first time. She said beforehand her mother-in-law had to buy "tickets" for her to go because her membership was only for her household to attend. What would that be all about? Do I need a ticket? How would I get one? I don't want to embarrass myself or be disrespectful.

Do you have a Jewish friend or acquaintance you could go with? That might make it easier.
