see what meal u eat la. inside mall basically same as Malaysia Pavillion mall those.

but road side simple noodle or rice could cost u 50baht easily so u need convert to RM by urself lo

1 meal 70baht with water average, mall different, mall 1 meal can cost u 150-200baht see what thing u order

try airBnb

Siam area hell alot of malls for u to shopping around.
Bkk is a nice place i don think u wanna stay inside mall for days...

try visit grand palace, chao phraya river, wat arun, asiatique on night time, khao sand road china town for night street food. Nana road /plaza for red light district visit.
besides that, still got alot place can travel around. try to use GRAB/UBER in Bkk to save ur money, if ur journey is particular in budget plan, otherwise normal Taxi meter would be good already.

TUKTUK car is not recommended as those people will open the price without standard to earn foreigner's money, so..my advice is take 7 days internet data and book/ wait for UBER all the way to your hotel room.

please note tat 5-8pm Bkk traffic is very very bad, not really advice u to travel on the road in this timing, but this timing u should visiting temple / mall/ street .

do feel free to pm me for more info u need

hi,
8 full days in Bkk is too long already, u do not need so many in this city alone.
if u with friends/ couple travel in backpack style, I would suggest MY>CNX>BKK>MY, 8 days is enuf to do this itenary:

4 Full day CNX Visit &
4 Full day BKK Visit

if Pattaya and Bkk for 8 days ok also, but not really adventure lor

Those temple u mentioned is the famous one already in Bkk. And famous only few xD

Floating market got a lot inside bkk or outside bkk or even at anothe province.

Since you wan within one hour one, I will suggest Kwan Riam Bangkok floating market. U need go google the location and how to go etc. Please note some market only open on certain day like sat/sun

Cheers

Yes. Even small road as soi, Uber able to reach your place. But during peak hours let say morning or evening, the road traffic will be very very Jam. So make sure u Don ffk Uber when they on the way to your place.
Fast is 8min, slow is 20mins. So u got to wait

Yes u can. Depend On ur GB. If 1 people use 1gb maybe last days, but few people shares maybe hours then gone. So depend
