1. Yes, Anchors Away parade. Can’t recall which days exactly, maybe day 3 and day 6?, check cruise compass once on board as it may change with your sailing. IMHO Best place is cafe promenade or sorrentos so you can sit and relax as you wait.
3. Welcome aboard party first night with midnight balloon drop if you can stay up that late. Variety of others - disco night, etc throughout the week.
7. Small wonders is only on the Oasis I think. Wonder has astronauts in various places.
8. Laser tag 2-3 times during the week when there is not an ice show or free skate. Sign up as soon as you board the ship via the Royal app. No problem also just showing up during the listed time and waiting a bit in the standby line as well. Closed toe shoes needed.
Not sure about the rest. Have fun!
