<human>: Can you provide a brief overview of the text?

My Mom [65F] has asked me to go on a cruise with the whole family, ages Baby to Gravelicker [1M to 78F]. This is about 15 to 20 people [depending on who is going to be coming] and my personal hell. Especially because 6 of them are kids. 

Mom is going to be paying for it, but since I [25F] don't make enough to want to spend it on day trips to a place I have been before [Alaska] it would be me on a ship for a week. I don't drink, I don't gamble, and I would be guilted into hanging out with children because for some reason they think I am cool. I am not. I am tepid at best and very unfriendly towards kids.

I don't like my family very much and do not want to spend a week with them over the holidays. I also have a 4-year-old dog I don't like to leave in a kennel. I usually go on trips where a dog can come. No dog allowed on this ship of dreams. 

I would have to share a room with someone [which I hate] and have to deal with family [who have kids.] So yeah, not my idea of a fun time. The problem is that my Mom has this dream in her head that the whole family will be together forever in memory, that the gods will smile upon our ship and use it as a beacon for love in the future. 

I don't intend to go... I am just not sure what the excuse and conversation should be. I know that showing what I wrote here would go over like a rotting whale at a child's birthday party. Lots of gross explosions and people being upset that Willy ain't what he used to be. 

How do I tell my mom I don't want to go on her hell trip? Thanks in advance.
<bot>: In an attempt to save my sanity, how do I tell my Mom I am not going on the Love Ship Family Reunion Tour Cruise and Labotomy?
