Looking For Ideas in South Central May/June 2019

Some buddy’s of mine and I are climbing and Skiing Mt Sanford in May 2019 and after I drop them off after at the airport in Anchorage post Sanford, on my drive back home to Haines I’ll be looking for some ideas for a solo 2-3 day packrafting trip somewhere between Palmer and Tok… class II-III. Don’t minda portage if needed and not shy of rugged foot or glacier travel either. Just looking to get some more adventure mileage in before heading off back to work. Any suggestions?
