Remember this might be your only chance to get to Alaska and you can't cut corners on everything. The prettiest place might not be in the best location. You probably have several options. For some that is perfect and an easy way to cut costs. A taxi might be more expensive than you think, if one is available.
Many cities have bus services.
Also you will need to add on your activities. Start adding these up and an all inclusive charter boat might be the best way to go, plus you can be out in the wilderness the whole trip and increase your chances to see wildlife and of course more of Alaska. Some people might say anything to get your business. Most are honest, some are not. Is this place interested in your happiness and desires or do they see so many people that individual needs aren't considered.
