I agree, since this bonus money is not needed in short term. Just put it all in low fee stock funds and let it ride.Perhaps consider setting aside some of this money to grow untapped for the future. Pensions are nice (I have one) but having sufficient investments / cash to fall back on as you grow older can help you sleep well at night.
Since your pension is more than your current expenses, you could consider investing all of the $300k and leaving it for the long-term and using the excess pension income for your travels. This way you've got a large chunk of money going to work for your future immediately and you can use the pension excess for fun in the short run.
Best case is you never need the money and can be distributed as part of your estate; at greater value thanks to growth. Or take withdrawals and use for your large expenses as needed or desired.
