PS Vita Traveling Help

Hey guys, I'm going to Mexico for the holidays and I can't take my PS3... So last year I bought a PS Vita to bring along to my trips and this year is no exception.. But I'm having some trouble... I currently own very few games (Injustice, Battle Royale, Minecraft, black ops, and Spider-Man, one with The GOW collection) I've wanted to buy FIFA( I'm a huge soccer fan) but I also wanted some accessories.. (car charger, Trigger Grips, and thumb grips) I have a very low budget of $20-$25 dollars:/! So I need help from you guys... What would guys get? Is there a cheaper price for this things or alternatives? The prices of this items are below. And Thank You FIFA Soccer: $14.99 or FIFA 13: $19.99 Trigger Grips: $14.99 Car charger: $9.99 Thumb Grips: $5.00
