Newbie. Planning early retirement Marbella area

My wife has retired and I could be totally or semi retired by end of 2021 and we want to come to Spain to enjoy the sun and european lifestyle, countryside plus golf , tennis and yoga.

Lucky enough to be in Golden Visa territory and will view villas and areas very soon. Looking mainly east of Marbella and close to coastline but not directly on it.

Would love to hear feedback on good locations, the level of social life all year round and any areas to avoid that go dead ‘out of season'.

Golf and tennis clubs combined options for increased social etc.

Also any warnings, traps etc to look out for?
