Cruising RCCL Ovation OTS in September 2023. Looking into excursions. Will have my husband and 3 kids with me. Cheaper to book White Pass direct versus extra $200 through cruiseline. Problem is timing. We leave Skagway at 5:00 p.m. Only time available direct is 1:00 p.m. If I book through cruiseline I can book 9:00 a.m. Worried we won't make it back to the ship in time for 5:00 departure or cutting it close. Any advice?
