The "Don T's 7-Rules for Travel" highlights the benefits of "organized travel". I like Organized travel. It's nice to "leave the driving" to someone else.
EVEN if I don't use a Travel company for a trip, I DO read their itineraries for help in generating ideas and "must do" sites. Often these travel companies have active FaceBook pages to tap into other people's experiences. (Gate 1 has about 4 groups on FaceBook)
One of the better resources I use is Gate 1 Travel company (I am NOT a paid affiliate of Gate 1). G1 offers trips at various price points to all 7 Continents. As of today, I've been on 14 Gate 1 Trips. They must do something right.
Want to go to Bhutan or visit Silverback gorillas in Uganda? I never even thought about Bhutan or silverbacks -- until I read they were possible via a Gate 1 trip.
Even if I don't use Gate 1 for a trip, I'll often check out their itineraries or Hotels. Most recently, I was organizing several days in Istanbul. I "kind of" knew where I wanted to stay (P.S. - on the European side), but could not find the right hotel on www.Hotels.com .... I checked one of the higher end Gate 1 tours for their preferred hotel and found a perfect choice, price and location.
Also, sign up for Gate 1 deals..... They have weekly specials with 20% OFF (or more) quite often. Finally, Gate 1 will also usually have several tours on their Last Minute Deals page.... Usually leaving within 60-days. But at up to (35%) discount, it's worth checking out.... I often do.
One thing that Organized Tours do very well is look out for their guests when things go wrong. It's February/March 2020 and I'm in Northern India/Nepal. We're watching "COVID 19" unfold and hear how the world is starting to shut down.
Guess what? We continued on with the tour, did EVERYTHING we had signed up, and made it home on March 15, 2020 just as the USA Border was scheduled to close.
THIS example - ok, admittedly extreme - shows the benefit of having a local team support you when things turn bad
I'm also a subscriber to Travelocity.com ...... Some great & discounted tours/cruises/hotels/destiantions are posted here. As a matter of fact, this was how I was introduced to the "Expedition Yacht" market and signed onto the SH VEGA for a trip to the Arctic. AMAZING discount.
Some of the other Sites I often check are:
Trafalgar (fyi- larger groups up to 50 and $$$. I'll never travel with them again)
EF Travel (younger tourists, often in Hostels ... Details Matter!)
OAT (Overseas Adventure Tours)
https://www.odysseys-unlimited.com (Small Group Tours)
Exoticca
https://www.busytourist.com
Tauck (premium tours, but at a premium price)
Vacations to Go
Luxury Escapes (Great for luxury and high end hotels/resorts)
Recently, I also used www.TourRadar.com to find my Douro River Cruise...... Pretty useful Site. A travel search engine that will show you many other Tour operators.
