I would say 2 weeks is not long enough to fit in a cruise unless you have done all the parks and looking for something different.
Last Easter we did 8 nights in a condo, 4 night cruise then 2 nights in a hotel. No problem at all, worked well but done the parks for years.
For us we love the Disney cruises more than the parks. We also enjoy
RCCL, nowhere near same entertainment as
DCL but when we are there 25 nights its great to relax 4 nights on a ship getting looked after.
If you haven't seen them 2 recent reviews and pics. Mine on the 7 night Western Magic

Now done 2 x 4 nights on Wonder and 3 x 7 nights on Magic, would go on either again but cost is getting a major factor for me. Just paid $3,000 for 7 nights this August, next August 4 night I would do is the same price $3,011.76, not paying that for a 4 night cruise, similar dates with RCCL $1,100
