Hello, I've been with my husband for 5 years, we have one child together 1, and he has a son from a previous relationship 15. Before the baby we have never been abroad the 3 of us due to finances and covid. This summer is a big birthday for my husband and I want to book a surprise trip for him I've saved up for. Our 1 year old will be coming but I can't work out the best way to approach asking my SS. I don't want the surprise to be ruined for my husband but I'm also not sure if our SS will want to come given his age and the fact we'd all share a room. For context the reason I'm worried to tell him before is when we told him about something similar a few months ago he slipped up (not his fault. Just kids being kids) Any tips and would you expect a child in his situation to want to come ?
