What To Bring To A Star Trek Convention? 3 to 5 items only, please

It has been more than 20 years since I’ve been to a Con, more or less.
One starts tomorrow, right here in town.
I will pick up some cash, at the bank in the AM, & go.
Can you give me a list of 3 to 5 items, that would be helpful to bring?

MODERATORS–please close this Thread.

The convention I attended with my family a hundred years ago said no cameras or videos. Of course, with today’s phones, you can get away with a lot.

Bring money. Lots.

A tricorder, a communicator/transporter beacon badge, and 1-3 bars of gold-pressed latinum?

Not going this time.
I took a look at the membership rate structure, & it is a rip-off.
Chattacon, con January, is a far better value.
