TK will only give you the hotel and visa if you are on the first flight out after arriving from your origin and the stop is >8 hours. Otherwise, you will need to pay for your visa to enter Turkey.

TG don't provide hotels, and the lounge close overnight, so you are better off going into the city to get a hotel (or at least an airport one). Also, when you get your boarding pass in BKK the next morning they might ask you to pay the 700THB departure tax. It really depends on the agent that issues your BP, but I'm about 2/5 for them asking to pay it during an overnight transit where I cleared immigration similar to what you are doing (both times at the J class check-in). No go for picking up your boarding pass at the transfer desk then clearing immigration either, they wont issue the night before.

Dont forget about the Egypt visa you'll need to buy on entry!

Otherwise, enjoy it!
