Cruising as a financial strategy?

Cruising as a financial strategy?

I have a third retirement income pending. If I delay taking it for five years I will receive $500 more per month. In my current situation I need the income but if I spend the next five years cruising, I could easily live on my current income. But... With inflation running away, would I really gain anything? Or take it now, cruise for five years but stick it in the bank or stock market?
