we [go]/[are going] to the beach every day

When you say we are going, you are using the present continuous tense. When you say we go, you are using the present simple tense.

According to English Language Centers,

We use the present simple tense when we want to talk about fixed habits or routines – things that don’t change.

We use the present continuous to talk about actions which are happening at the present moment, but will soon finish.

So, if you are talking about habits while on vacation, you should use the present simple tense.
