If you're feeling industrious, work out your whole weekend schedule. Descriptions of all the videos, panels, and events can be found in the program, so look up info on something you are unsure of. Taking a little time early to plan ahead will save you more time later, and you'll miss less stuff. As for specific events, the Balticon Masquerade is often considered the highlight of the convention. It gets the prime Saturday evening time slot, and it is probably the most heavily-attended event at the convention.
Some people line up hours in advance to get good seats.
That's their choice, but they miss a lot of the convention by doing so. The con suite is a mystery to some newcomers. What it is is a room you can go to to relax, sit on a nice comfy sofa, and eat free food and soda. You can also talk to your fellow fans while you're there, but free food is the main attraction. Snacks like chips and pretzels, soda, coffee, vegetables, chocolate and candy, and other snack foods are usually available.
