The job you describe, in a general sense, I could not do.
Yours, specifically, sounds OK. For the right personality type.
The always-being-around-people part alone would devastate me. I’m an incredibly solitude individual. A natural loner, essentially. I don’t mind being around others, but only for relatively brief periods of time.
I not only enjoy being my myself, it’s completely essential to my mental and emotional health.
Oh I've seen people completely loose their minds working here, no joke. It's not like a normal job where you can go home to your own sanctuary at night, here you have a rough day and go to your room and your roomates are playing video games, having sex, listening to music, drinking, all kinds of fuckery. You have all kinds of different personalities underneath one roof. People tend to quit mostly due to the actual ship life not necessarily the job itself.
has someone from getbig ever met you on the cruise ship?
Lol, dude theres like 10-15 active Getbiggers, I have met a few in the gyms one guy in Hawaii came up to me and said "hey you're Go 4 It right" lol I just started laughing we chatted for a bit, he was a good dude, black guy, but said he never posts, just lurks, but this was like 6 years ago.
Starbuck or McD is for tourists, Thais would never pay 155 B for cappuccino, I buy small ice espresso can for 15 B (1 A $ = 25B)
Hardly anyone eats at Pizza Hut. Permanent Expats don't eat in those establishments or buz in Roo or Irish bars.
I am mostly in Phuket , Kamala beach & occasionally in Bangkok ,on 90 days visa's 
My monthly gym fee is $ 28 & no Farang members , + Muay Thai gym 2X p/w.
From what I saw when I was in Bangkok, I was staying in a condo across the street from a McDonalds, the place was fucking packed day and night full of Thai's dude. Everytime I would go to Terminal 21 I would see tons of Thai's eating Subway, Ice Cream. But most Thai's look at sticky rice with mango as a cheat desert, compared to Americans eating cheesecake as a desert. Phuket is awesome, I trained at a gym called Patong gym there, it was a small gym, but had enough to get the job done, it was like 30 baht a day.
