Is Marbella open ?

Marbs is always open, although some restaraunts and bars may be closed. Xmas day likely everything closed and also most shut early on xmas eve as well.

Yes, largely everything is open pretty much as normal, or the new normal anyway. Be aware that masks are currently mandatory for just about everything other than sitting in a bar or in a restaurant but you'll soon get used to that. Keep an eye on local news sites as with everywhere else it's a fluid situation that can change from one day to the next. But right now, life is as normal as you can expect in these times....

Thanks , I was thinking more of the Covid situation .
