    Our CEO, John did an amazing job. I also appreciate the kindness of the local guides. The trip was great overall, and I gained knowledge about culture and history not to mention the beautiful places that we had visited.

    Great tour, great scenery. It won't include much nature, mostly cities/towns/villages. Definitely at least once in a lifetime trip with many memorable moments - sunsets, beaches, lively towns, historic sites like Bayon temple (loved it!), massive caves like I haven't seen before, really beautiful sunset scenery when paragliding, gorgeous mountains you get to climb etc. It was really great. The accommodations will be very basic but expected given the price. It'll be very active as you'll be spending a lot of time on the road every 1-2 days, perhaps a "chill" day every few days would make the trip less exhausting, especially when you're doing this for a whole month, as you'll be drained by the end, not ideal! The main gripe would be the constant guilt tripping and even blatant "it's not cool to tip less than we tell you" messages from tour guides. Constant pressure to tip, which I'm ok with to an extent, but, let's be honest, the demanded tips were way too much in some cases. And the "we are very poor that's why it's your obligation to throw your hard earned money at us" speeches that would last up to an hour need to be toned down, especially when people aren't that poor, just living like everywhere else. Personally I didn't work hard to afford once in a lifetime trip to be constantly nagged and be treated like a cash cow when I've already paid and I have little doubt that generous tipping was already included in the overall cost. With that said the tour guides were overall very friendly, accommodating. Zero issues with transportation, though do be ready on occasion to be drenched in sweat the whole day and jump into a train without a shower!

    Alice

    Asked on November 29th, 2024

    My girlfriend and I are keen on joining the 40 day tour of South East Asia. We are wondering if there is a possibility of us being put in a private room together and what the extra cost would be. Also once finishing are you left in Ko Tao? We are hoping to fly back to the UK from Phuket on 26th/27th June. Do you know of the best transport to get there?

    Accommodation
    Flights / Transfers
    • G AdventuresOperatorWritten November 2024

      Unfortunately we do not have the option to offer private rooms in many of the stops, so it would be in same gender multi share for those nights. We offer an add on of 'Bangkok Express: Ko Tao to Bangkok', so you could easily get back to Bangkok to fly back to the UK from there.
