General Question about strategy with loose/semipassive table

[RIDGE45]

I play 4-8 at a B&M, and the table today was fairly loose passive, with one semi LAG.

Now my question involves general strategy at particular tables. At this table, there was average 4-7 players per flop, and if it was raised it was rare for blinds and any limpers to fold.

So my question is how much should I loosen up at a table like this? Should I raise marginal hands in position (KJ, K10s, AXs, low PP, etc) and I should a limp marginal hands in EP?

Basically, how should I adapt to this situation where there are quite a few people to the flop?

If this table is passive (not many reraises of bets) should I bet out draws, etc?

Just wanted to see what people's opinions where on how to adapt to certain table types.

Any thoughts appreciated.
