Review Everest Base Camp Trek: Worth the Investment?

I came across a 14-day Everest Base Camp trek package with A Nepal Planet Treks for $1,400 per person, which includes guides, porters, accommodation, permits, and meals. Sounds like a great deal, right? But I'm curious about other costs like international flights and travel insurance that aren’t included. Has anyone done this trek or a similar one? How did you find the overall experience, and do you think the investment is worth it considering the additional expenses? Any insights would be helpful!
