Our target audience is very broad, since we will cater for anyone going on vacation, looking mainly for a place to stay (from a hotel to a house to rent), but we will also list restaurants (to eat) or clubs and bars (entertainment).
Think a web 2.0 site, very modern layout, I really like airbnb.com. I know this is for logo design, not web design, but I really like their website.
We have a slogan, it's in portuguese, but we could translate it as this:
"Find out now a place to stay, to eat and to have fun. Simple. Fast. Free".
The logo can incorporate this slogan or not, we're really open to ideas here. Be creative =)
