Any ideas for a sweet 16 party, at my house?

So my birthday is tommorow , but I am thinking of having the party this coming saturday. Ok so these could be the people I want to invite, Alda (lives like 2–3 hours from me and a good friend of Anna aswell, so I was thinking she could sleep at Anna’s), Anna, Agnes, agla, linda,(she’ll go on a trip, but it’s fine even if she misses it, kinda annoying-not being mean), me, Siwanart(45 minutes from where I live and we aren’t so much in contact either), birta, þórunn. I was thinking of everyone coming while looking their best. Food would be something mexican, you just choose what you want and put on a plate or just order Domino’s Pizza. Games-maybe cards, I have no idea or something to play since we’ll all look fab! I hope and also should I have a cake or what?

Sorry it’s soo long:(

Anyway tell me what you think of this idea? and you can ofcourse add some suggestions if there is something missing and I want it to look nice but cheap also.
