I wish I could give you a straight answer on this! I will say that I'm not really interested in being part of the Get-Together as a whole, but would just like to join that Archipelago separate from the Get-Together. It's entirely possible I could be completely busy for an entire weekend sometime in June, but I don't know exactly when, or if it's even happening in June at all. If it's part of the Get-Together I wouldn't want to say "Could you delay this entire Archipelago a week because I'm busy", but if it's just some Archipelago you're running as its own thing, I'd probably let you know as soon as I see it if I'm available or not.
Tl;dr, I'm pretty sure I'd be available throughout those months, but there's one weekend I definitely won't and I don't know when.
Funny I find this out the very next day: if it's anytime after the first week of June I'm pretty sure I can promise full availability for it like usual.
