Not sure of your point of origination, but you could drive or Amtrak to Seattle, then Seattle-Alaska (inside passage)-Seattle or (Amtrak and Sky Train or charter bus) to One Canada Place and Vancouver-Alaska (inside passage)-Vancouver with HAL. May is a discount month, but the weather can be misty/rainy. If looking to round trip to the interior, then up by a HAL cruise ship and back by another cruise ship or ferry is possible - ships don't roundtrip the interior and people tend to disembark and train up to Denali or do land excurions. Rumour has it that Alaska is nearly as big as Texas so excursions tend to take more than a day.
