..... on the Main Street (N10) in Taliouine there's a modern building on the south-side, its a cultural/ agricultural, museum with exhibits etc., development association and interacts with tourists, the best quality saffron can be bought here including Argan Oil.

Taliouine is divided by a river, the old village and busy souk is south of the River, while the N10 road was developed on the north-side by-passing the long linear old village. For the most part crossing the river is a stepping-stone exercise, one bridge for vehicles at one end to the village.

The downside of leasing the lodges to outside operators is that they are not familiar with the region, routes, villages, weather patterns etc. So asking them for advice about those things might be pointless.

We have stayed both in the GCNP Village, and Tusayan, and each has its advantages.

Being near the rim is nice, but you get a better room and facilities in Tusayan, and it's only a couple of minutes out. We've stayed at both the Red Feather Lodge, and the Canyon Plaza Resort ... they were fine.

September is still peak, so they won't be cheap. Make sure you see sunrise and especially sunset from one of the rim lookout points - it's magic.

And yes - which way do you go after Bryce Canyon NP? I agree about including Zion NP, but I wouldn't do the long drive to Capitol Reef NP, unless you're heading east anyway.

Its not always that expensive to have drinks at a restaurant or guesthouse. You can also buy beers at a 7 11 or similar store and bring back to your room. You don't have to just eat street food its not that expensive to eat at simple restaurants.

Okay great then I'll do that, thanks for all the tipps!

You acclimatize faster without air con , fan rooms are enough. However some hostel dorms are air con and not expensive (not available everywhere). Once upon a time everyone on the islands stayed in wooden bungalows with no electricity.

Makes sense :D So I'll just try to get used to it and then it's probably gonna be good.

Buses from the bus stations are not that expensive. If taking any tourist buses do not leave any valuables in stowed luggage.

Yes found the prices on 12go.asia quite cheap, too.
Good to know with the valuables, gonna look out for that, thanks!

Yes you can but don't go to expensive places and travel in traditional budget traveller style. Its also not that expensive to travel in Malaysia and Sumatra in Indonesia and the weather would be okay for the time you are going. But to fit them in means a longer trip. You could also save more money and have a longer trip at another time.

I suppose with traditional backpacker stile you mean cheap hostels and so on?

About Malaysia and Sumatra:
I haven't really done any research on those countries yet, so I'm also gonna do that.
Do you mean that it would be cheaper to travel there during the trip and spend some part there or do you mean to just spend the whole trip in Malaysia and Indonisia?
Also flights seem to cost around 80-100€, so the question would also be, so do you think it's worth it to go there?

About the weather:
My research on wether and seasons is mainly based on the data on weatherspark.com.
Is that a site you would recommend or are there other (better) sources?

From what I've found there, August is pretty much off season in Thailand, does that make a big difference?

Also, the more south you go, the muggier and warmer it obviously gets, so is it better to stay more in the north of Thailand or go south?

Then on a third note, it looks like it'll be around 90 to 95% overcast and 60 % precipitation.
Do you think this is an issue or would recommend going to Thailand at a different time?

Go in Tajikistan, just on the other side of the border, where you are free to hike in many remote areas ! Or in Kyrgyzstan. There are homestays in some villages.

October to the end of year is not the best time to swim wherever it is. Or you look for indoor or public pools. What do you think about to take a ferry and spend some time on Corsica (with or without a car). Most time of the year the weather is a little bit warmer than on the continent too.

The last time when I was there in February (more than 10 years ago), I stayed in a (obviously open) hotel at Monterosso. There were open restaurants in all 5 villages.
The weather was sunny and dry, with temperatures up to 20 degrees.
A few years later, in February too, most trails were closed because of inundations and landslides after heavy rainfalls.

As accommodation will not be a problem in February, I would just wait until the last possible moment, consult weather forecast and webcam pictures and decide....
