Hope I did not make a mistake!

What ship are you sailing? Some ships' Solarium has a small pool in addition to the hot tubs, but not all of them.

Anytime schools are out you have the potential for lots of kids on any of the big 3 cruise lines, Carnival, Royal and NCL, plus of course the Disney CL. We tend to cruise when schools are in session on these lines, but even then there are children on board, not as many, but always some. Because of the included on board activities centers offered by these lines there is enough attraction for parents and grandparents to sail with young kids.

If looking for cruise lines with a reputation for having less kids on board anytime of the year than the 4 lines mentioned above you need to look at Princess, Holland America, Celebrity, AIDA Cruises, Azamara, Costa Cruises, Crystal Cruises, Cunard, MSC Cruises, Oceania Cruises, or Regent Seven Seas. But on several of these you lose the activity involvement attractions like mini golf, waterslides, rock walls, sky bikes, rope course, and surfing simulators. Instead they offer things more like cultural enrichment seminars, enhanced dining, golf simulators, and classes on things like cooking, painting, digital photography, or ballroom dancing,

Viking Ocean and Virgin Voyages are reputed to be for adults only, but are very small lines as of now (only 1 or 2 ships). As they build or convert more ships they might decide to include more of the activities that are popular to adults from the big 3 cruise lines.

Depends on the RCL ship as to what the Solarium has and who it is open to. I can only speak for Anthem and it has a series of beautiful small cascading pools for soaking in (too small to swim in) and is open to all adults. I understand that on the Oasis class the Solarium is only open to adults with a set crown & anchor level.

I've sailed on several Royal Caribbean ships in many different classes. I've never found one that didn't have a pool in the Solarium. Some were indoor, some out, but all of them had one!

Radiance of the Seas: indoor

Explorer of the Seas: Outdoor

Vision of the Seas: Indoor

Liberty of the Seas: Outdoor.

Do keep in mind that in bad weather they sometimes allow kids in to the solarium to enjoy the indoor pool for a few hours (but not all day).

Viking Ocean actually has six ships now and I HIGHLY recommend them if you can afford it and don't mind not having all the bells and whistles! I was only 24 last year when I sailed and it was the best cruise I've ever taken.

The larger RCL ships have pool and whirlpool in solarium

Solarium on the Oasis Ships is open to anyone 16+, no C&A Requirements.

A cruise is to be enjoyed. There are several areas and venues on a ship one can go to if one wants to avoid the energy of kids.

Usually there are "adults only" areas such as pools or spas somewhere on the ship. I don't know the ship you're going on, but I'm going on Adventure Of The Seas, and I believe there is an adults-only pool area.

I would agree with cruisellama. I saw a video of the one that I will be on in August. The larger the ship is, the better in my opinion. There should be an all adults pool area.
