My family is looking at booking and Alaska cruise in early April 2024 (7 day round trip from Seattle on Norwegian Sun with Glacier Bay). Does anyone have any experience with Alaska that early in the season? We know it will be chilly and are experienced skiers with thermal gear, appropriate underlayers and shells etc. but we wanted to know if port activities, excursions shops, etc would be open that early in the season as it appears most other lines don't start Alaska cruises until late April or May. We are scheduling around our kids spring break so can't do later in the Spring (and have an obligatory family trip in the summer so can't cruise then either). Thanks for any and all tips and insights!
