Which resort is the best for pool time, resort time and food options? Where would you stay in summer with a resort day, Caribbean Beach or Coronado (not the tower)? Thanks
CBR has better transportation with its proximity to Riviera (for other much better food options) and the skyliner. Comparing main pools, CBR/CSR are similar and they both have quiet pools. I have never found one pool to be nicer than the other. I believe that CSR has a longer slide than at CBR, not sure if that's important to you or not.
You have access to decent restaurants at both on site, Sebastians at CBR and Three Bridges, El mercado, Rix and several really nice lounges at CSR. Where the differences really show are the rooms. CSR had a refurb not that long ago and the regular/non tower rooms are much nicer than CBR. The rooms at CBR were last redone I think 3-5 years ago and while that doesn't seem that long, in disney years, that's like a decade of guests using/abusing rooms since they turn over so many.
We spent a week at CBR last summer and we thought the rooms were in pretty bad shape. The CBR lobby is nice as that's been redone in the last few years but the lobby at the CSR Tower and lounges are so gorgeous and do not compare to CBR at all. It truly feels deluxe compared to what it used to be.
CBR is also a bit larger so there is more walking involved to get around. And do consider that since you'll be there in the summer, as great as the Skyliner is, it stops running for inclement weather which is fairly often. Transport on buses when the skyliner goes down is never seamless. I think generally speaking, it really comes down to your personal preference since they're fairly similar. Which theming appeals to you more, will you want to use the skyliner and what's most important for your stay? For us, we are CSR over CBR. Not a popular opinion but the Caribbean theming isn't our vibe and I can't justify the cost for those rooms at CBR especially when the rooms at some of the values like POP are nicer, cleaner and newer.
