With this website, you can spend more time having fun and less time searching for what to do.

Peek.com highlights activities and tours in 17 U.S. destinations, London, and Paris. You can explore activities based on themes that first-time travelers might be interested in, such as Sightseeing, Food and Drink, Walking Tours, Off the Beaten Path, and What to Do When it Rains, as well as topics that locals and returning travelers could use, such as Day Trips, Romantic, What to Do With Kids and more.

What's hot: It's an instantly inviting, well-designed site. You can quickly access activities that are available this week, if you haven't booked tours in advance. There's even an under-$50 category for bargain hunters. Make sure you search beyond the Most Popular Activities within a city and check out the Perfect Days section, where you can find celebrity itineraries. I agreed with Piers Morgan's Family Travel picks for San Diego. Not currently on a trip? Sign up free and save items to your personal wish list.

What's not: No major complaints, but I hope it adds more destinations soon. I'll be back before every trip.
