Glacier Bay and Hubbard Glacier are very similar. The big difference is that Glacier bay is usually and all-day visit as Hubbard is less then 4 hrs. With Hubbard you get to spend an hour near the face depending on how many ship there . Depending on the season Hubbard Glacier doesn't open early enough to let ships approach the face due to ice berg bits or ice floes.
