The ultimate weapon for chicas is akin to the hotel nicey-nicey kits you find plus obviously the electronics.
Here's my beta kit:
-> A digital music player. In this instance, I hate apple Ipods with a passion. And yes, I'm in the computer business and have been for 25 years. I can tell you honestly that any time you buy an Ipod, Iphone, or Imac, you're in essence paying for cool design and the pop/cool/hip factor. This is a discussion for another subject, true, but my point here is that almost any digital music player (with decent play list control, and decent storage options) will work fine. I use a cheapo $79.99 Walmart special with 2GB of ram and a play list controller. Plus is comes with FM radio.
-> Speakers. A micro setup will work, radio shack carries these. Usually powered in each speaker (left/right) by a small 9V battery. Obviously, for the audiophiles in the house, any 'speakers' simply will not do and we'll see them with $1K Cerwins or similar. My choice will be

-> Music. A 2GB mp3 card is a great tool to fill up the novia-de-momento with wonderful sounds as you fill her with your other tool. [OY QUE RICO!] I've got a selection of reggaeton, reggae, rock, some rap and hip-hop and now a large selection (and growing) of classical. Add to this a new-age, retro and some new indie rock, and she'll be left with no choice but "Claro, Papi" as we rock and roll and rock the boat some more.
-> Small candles, tea-type. Maybe 5-10. Ambiance is key, no? Either scented or not, if not scented, then ...
-> Some incense. [CLARO QUE SI]
-> Love beads -- ok, ok, I'm going too far. But seriously, why not?
-> Scented massage oils. (SOMEBODY STOP ME)
Whew. I went from one small carry-on and a duffel to about 10 30-gallon luggage 'bags' (the kind I see people buying crap and taking back with them, these luggage toting folks have the system down, I tell you). I probably need to trim my options and choices here, but in all honesty, if the foregoing stuff can get your lovely darling wet, ready and in the mood, that $[insert charge here] you just spent to unload your worries and bide some time between beers with the fellas will be much better spent, IMHO.
