Just a question, is it worth upgrading my standard view to preferred view in order to request Martinique or Trinidad North for an extra $381 for 7 days. DS (4 1/2) will be in a stroller and I worry DD 8 1/2 will be tired from walking all day in the parks. I don't want to struggle to get back to the room every night and to get to breakfast every morning. Any thoughts? Thanks
