Hopefully the days when we can freely spend our time outside will come soon
"Hopefully"=「望むところは」
"the days when we can freely spend our time outside"=「自由に私たちが外で時間を過ごせる日々」
"will come soon"=「近いうちに来る」
「心置きなく」という部分ですが、"without any reserve"という言い方もできます:
"Hopefully the days will come soon when we can spend time outside without any reserve."
