But it seems to me that it shows "will be going to get ...", not "will be going to [place]"
I agree with you Hirashin that that last sentence is of the "will be going to (do)" variety
the original writer may have intended, or have been thinking of, "will be going (to Wat Bang temple) (in order) to get a tattoo but they wrote, and initiated the thread, with "Hi, I will be going to get a Sak Yant done in November" which in writing is wrong, and looks horrendous.
Do you really go around saying "No. Wrong." to people in real life?
Sorry to interrupt you, but would you tell me whether native speakers ever use the pattern "will be going to do something" ?
A future event can be expressed with "will [verb]" (e.g. "I will eat") or "[be-verb] going to [verb]" (e.g. "I am going to eat"), but not both.
Your sentence: "I'll be going to stay home." is equivalent to "I will be going to stay home." This uses both future grammatical constructs combined together, making it clearly incorrect.
It can be obvious what someone means even if they have used wrong grammar. You can't headline a thread "Toyko" and then write "I am go next year" and justify it by saying it's obvious what you meant.
Err, yes. That sentence is back to the original "will be" + "going to (do)", which we all know we don't use, just as you quoted 3 posts above.
There is no implication whatsoever that the speaker is travelling anywhere to see it
Where is the implication?
