Vegas resort recommendations

Hi!

My friend and I are coming to Vegas for the first time in July and we were wondering if anyone can help us in choosing a resort.

We are currently between the Bellagio v. Cosmopolitan v. Venetian

For some context, we are in our early 20’s and are planning to go for pool parties, clubs, and to try out good restaurants in the area. We are planning to go for a week but really, we just want a place that’s going to have nice, clean rooms; central to the fun areas; prefer to have nice amenities (pools, restaurants…). Curious to hear what might be the best option or if there’s any other resorts we should be considering.

Thanks!
