Party or alone?

There is a bonus for playing multiplayer that can make a big difference, but it's ultimately your choice. I'll provide some information about that bonus from our game guide, though, so you can decide if you think it's worth it or not. :)

While enemies grow in power with each additional party member that battles nearby, the rewards heroes receive from working together to defeat these foes also increases. In addition to bonus chance to find magical items and bonus gold received, you also receive bonus experience. This experience bonus is multiplicative with difficulty bonuses, so playing multiplayer at higher difficulty levels yields even greater rewards.

The experience is additive not multiplicative,

For clarity, each stack of the "Strength in Numbers" buff is additive (so, 10% for 2 players, 20% for 2 players, and 30% for 4 players), but the bonuses provided by the buff will actually stack multiplicatively with other bonuses (like those you get when playing in different difficulty levels or from Pools of Reflection, for example).
