I'm hosting a documentary watch party and am stuck on the menu. Please help!

The party will begin around 3 pm and since people will sit on the couch or bar stools I'd like the food to be portable. So far this is what I'm planning:

SIPS- limeade infused with mint & raspberry
* still debating if I should provide Vodka or Champagne to spike OR serve wine OR ask people to BYOB to share WDYT

SNACKS-
chips & salsa bar (use paper trays to serve)
* yellow & blue tortilla chips
* guacamole, tomatillo salsa, corn & black bean salsa, fruit salsa, cojita cheese
**really guac & 3 salsas & cheese topping

SWEETS
- chocolate covered pretzels
- fruit mousse topped w/ real fruit (use mini shooters & spoons to serve)
**Not sure which fruit yet; I have only made vanilla bean mousse before.

Do I need something else for the SNACKS? I love pita & dips/ crostini & toppings, but is that too similar to chips & salsa? Everyone coming does eat meat.

This party needs to be budget friendly.

ETA: what's the best approach for the SIPS?
