Can We Have Joint/Group Aliyot?

I recently started attending a shul that gives joint aliyot. What, if any, are the halakhic issues with two people receiving an aliyah at the same time? Do any of the issues rise to the level that I should privately request only solo aliyot from the gabbai, or perhaps even ask not to receive an aliyah at all?
