We are planning to go on the Dream next year and before I book this I wanted some expert opinions please. I am fairly sure the dates I am booking are firm, HOWEVER if I have to change them to another date within 75 days do I loose money? I am looking thru a guide book right now and the info seems confusing to me. Next, Do I request my dinner seating when booking? I really want 1st cause I know DD cannot do dinner at 8ish at night. Third (I don't have to know this before booking but it would be nice to know), I was reading I can take care of my tips online BEFORE boarding? is that right? I remember reading about going to take care of them earlier in the cruise before later to avoid a long line but if I can do it from home I am psyched. 4. Guide book I am reading says that I can request my fridge for medical reasons when I book, but I thought I read I have to fill out some kinda form to fax in? I know I request it on the phone if I am going to the WDW resorts but not sure about cruise.
