I need help with my Budget...am I over budgeting?

*Monthly**

1. Rent $700 (all in for utilities, water, electric

2. Transportation $400 ($100 weekly)

3. Food $900 ($10 3x a day = $30)

4. Phone & WiFi $100

That's $2100 mandatory bills....

I still haven't

1. Clubbed/Partied

2. Tourist/Travel/Island Hop/Elephants

3. Shopped for new cloths for climate etc

4. Girlfriend Experience

What else am I forgetting????

My plan was to take 20k for a 6 month vacation 25k total with 5k for flight and and visa fees & insurance;

Pay bills in America for 6 months = $6000

14k ÷ 6 months = 2333 remaining Budget

70k savings getting 4% in high intrest saving account pays me an additional $258 monthly bringing my total BUDGET to $2591 ($2600) monthly.

With $2100 in MANDATORY bills that leaves me $500 a month to party/massages/island hop/ elephants and if push comes to shove "girlfriend experience".

Am I OVER or UNDER BUDGETING....AND WILL $500 a month be enough after MANDATORY BILLS are paid to have the kind of adventure that most are looking for?

P.S. I'm 44 so even tho I look foward to some night life nights....I see myself being more of a "visit the islands" lay up and get massages 6x a week and eat good food and visit cool locations over the club scene. But I do party....
